SG33G5B [silent-on air] 8800GT Passive Cool No case mod

[f5inter2]

Here is the side view as proof that there is no case mod and also it fits.  I have 8800gt without the annoy sound




Here is a side view, as you can see the VNF100 zalman really fits.





Here is the GPU with a cooler and I tied on a 60mm coolmaster fan running with resistors to make it slow.(i don't want any sound)



A top angle view, don't know if you can see the GPU/cooler



Here is the back, As you can seee you can't use the PCI slot




Yes as you can see I have upgraded from this P4 Qbic computer hahah  this thing is liek 4 years old.



Here are the temps, yes my GPU is 256Ram becuase I don't want it to consume that much energy on a 250W PSU

The Graphic card is 8800GT gigabyte with
Zalman VNF100- Passive cooler

I switched all fans to Nexus except this Coolmaster small fan.  The coolmaster fan has resistors to make it under 20db (can't hear it)

I swaped the PSU 250W's fans with the MINIKRAZE scythe fans 40mmx20mm

The 92mm fan with the Real Silent Nexus fan 27CFM 19.5db

THe entire system is silent from 3 feet away.

The load gpu never exceeeds 75C  and is completely silent.

The fitting will take some skills to put, you have to put the drive/hdd tray then put the card in place, then lift the drive tray up a bit just enough to push the GPU in  then you put the tray back down.   Basicly no one can take you GPU and they can't steal your tray either if they don't take the gpu out in a special way.

No case mods.  

My 3dmarks are 11,500 ish for the 3dmark 06.

Very nice work!

I have been thinking about doing something like that to my shuttle once I get my Rogue up and going in the next couple of weeks. I have one question for you can you put a tape measure to the top of your 8800GT video card and tell me how much clearance you have between the top of the card and the drive tray I have been thinking about the Thermalright HR-03 GT cooler and it would help to know how much room there is between the top of the card and drive tray for heat tube clearance.

Thanks

ShadowTester:  
Hey, I've looked into the THermalRight HR-03 GT   it won't fit, this zalman VNF-100 barely fits (basicly it's a very very very snugg fit)  the thermal right is bigger, thus won't fit unless you are willing to cut your case.  just use the vnf100  it's not a problem seriously,  this thing is completely silent the flourescent lighting makes more humming noise.  The idle temp is 50-56C tops and the load temps (playing lost world on max settings or running 3dmark 06) is max 75C and usually is 68-71C)   Keep in mind this is COMPLETELY silent from 2-3 feet away.  Infact you'll hear the harddrive being louder than the fans.  To adjust the fan speeds use resistors that will lower the voltage into the fans, you can make them or buy them.  they are molex male and female ends.  Anyways whats' wrong with VNF100 zalman?  you think thermalright is better just becuase everyone says so?

[Maturin]

Welcome to Sudhian, f5inter2
I like the fact that this cooler fits in the G5 a lot. One question though, is what would temps be like without the extra fan? Since the ICE fan pulls air out of the case, I was hoping some of it would go in through the side vent and pass through the vnf1000 on the way to the ICE fan.

[Shadowtester]

Biggest difference is Zalman has 3 heat pipes where the Thermalright HR-03 GT has 6 heat pipes so it should be able to transfer a greater heat load from the card in a shorter time period which should result in a lower temperature. But you did answer my question from the pictures it looked like the Zalman was a shoe horn fit and the Thermalright being larger looks like not possible without extensive case modifications.

[f5inter2]

Shadowtester:  in short the thermal right won't fit sorry to burst your bubble, becuase i already tried the thermal right.  VNF100 only way to go

Maturin:  the temperatures on completely silent with no extra fan is 65C idle and 85C on load, if you choose to put the fans settings to spin on LOW  then the temperatures are 55-60C onidle and 70-75C on load.  Just ask more if you need to

I took your advice I have the rest of the components I need to put my shuttle back together for use as a HTPC and a gaming PC for my bedroom. I just ordered the CPU and a 8800GT along with the Zalman VNF100 I already have a extra 92mm fan I can use. This PC might also see some time as a folder as well when not being used for HTPC or gaming in my bedroom

SG33G5B future stats
Intel Core 2 Duo 3ghz over clock? from the reviews of the cpu many have stated 4ghz is pretty easy to achieve
Muskin DDR2-800 2gb
Samsung HD501LJ 500gb Sata
LiteOn Black DVD±RW

[f5inter2]

SHadowtester:  Yes I knew the E8400 Can over clock very easily, But I recommend you do not over clock it.  THis is why, the increase in performance from 3ghz to 4ghz will most likely be not very very noticable, I'm saying that becuase 3ghz gives me 11500 3dmark06.  If it' s 4ghz i might get an extra 2000 points.    

Keep in mind the psu is only 250W I connected two different rails to power the gpu (so it's like using two lines and adding them up to power the gpu)  the system is already underpower I don't think over clocking is a wise idea.  Anyways you can certainly try and see if you can get it stable, but i'm afraid you might kill the PSU.  

Post pics of how your mod goes when you do.  Also you might want to invest in another fan to tie onto the VNF100 like what i did, it really helpe dthe temps by 10 degrees.  but you might have to get those (resistor adapters) unless you find a way to control the fan2 slot and if you do find out please tell me.  Thanks!

[liaeb]

hey gents, wondering how you think this would fair in my setup? My 8800GT is to noisy for comfort

[Shadowtester]

From the pictures I was able to find of the interior of the SG33G6 it looks like the same basic case and mother board layout so I do not see why it would not work.

I already have a few extra fans to try and use on the Zalman heatsink since I replaced the 92mm fan on the ICE with a par of 92x38mm fans in a push pull setup to help cool my Q6600 which I had over clocked in the shuttle at 3.3ghz I was using those fans at 7vdc which were pretty quiet and kept my Q6600 while running at 3.2ghz folding with 2 smp clients in a room with a ambient around 72-75F in the mid 40c range. What kind of modification did you have to do to power the 8800gt from the shuttle's power supply any pictures would be appreciated for the insight. I know I have at least 1 40mm,60mm, 70mm, 80mm, 92mm, 120mm fan laying around I should be able to come up with something that will work

[liaeb]

Thanks Shadowtester!!

The G5/G6's internals do look pretty much exactly the same from what I've seen also.. I may just purchase this cooler

[f5inter2]

Shadowtester:  Hey i don't have time these few days to take apart the shuttle as i've mentioned it's a pain to put together and to take apart haha , but if you give me a 3-4 days i'll have time to show you, since i have to put in the OCZ coolant.  (school started for me hahah trying to buy books to photocopy haha as i am a poor engineering student, plus i used my book money savings to get this computer hahah)

But quick answer,  You know the shuttle PSU comes with those 2 x 4 pin connection on one rail  and another 1 x 4 pin connectors on another rail.  All i did was take 1 4 pin connector from each of the rails and used that to power the 8800gt,  basicly what I think that does is in theory those two were designed to power two seperate things  (well one rails actually was designed to power two things the 2 x 4 pin one)  so i figured if i put them in Parrallel the current will increase and hopefully that's enough to keep the 8800gt stable, which so far it's been stable for 1 week and i haven't turned it off.  I installed GRID  lost plannet and played all on max settings hahah  lol  so far when i put the settings TOOOO high my gpu will go to 79C  but will idle back at 55C in a few minutes after i log out of the game.

[Shadowtester]

I understand what your saying and I looked at all the connectors I got with my 8800gts cards for my other computer which has a dual 4 pin connectors feeding a pcie connector, When I first read what  you said about modifying the wiring to feed the card I thought you had to actually cut and splice the power supply wiring to feed the card but after discovering that adapter the power supply wiring should be very easy. I also purchased a 350 watt sparkle 1U power supply for $53.00  to upgrade my shuttle power supply should not be very hard to do from the info another member supplied when they modified their G5 shuttle with a sparkle 300 watt 1U power supply just some minor dremel work to the back panel and then I should be good to go power wise

[f5inter2]

OO Shadow Post how the 350watt goes, becuase I sorta want to upgrade the PSU I don't like the idea of having things underpowered. hahha  Post some pics.

[Shadowtester]

Here is the link to the G5 case sparkle 300 watt power supply upgrade for you to look at I will try to take some pictures when I do mine as well

Well I have updated my SG33G5 with a 8800GT using the Zalman cooler while folding it holding steady at 57c I still need to get a fan to put on the heat sink so I can try some over clocking on the card the only 60x25mm fan I have was really noisy. I am going to get a 60x25mm PWM and hook it into the video card fan bus so the card can control the fan and only ramp it up when necessary. Great mod thanks for the idea and pictures.

[liaeb]

Hey Shadow thanks for posting up your results.

Isn't F@H more CPU intense? Could you post us up some load temps (using Unigine maybe?)

Still 57c still is idling lower than my 61c and I'm sure ALOT quieter

Thanks

[Shadowtester]

That was using the F@H GPU2 client which puts a very heavy load on the card close to maxing it out so that was a load temperature I have noticed on a couple of GPU2 client wu's that the temp has gone up to 61c but the ambient temp in the room was also higher so that could have been the cause. When I was using the noisy 60x25mm fan a simple 2 wire fan running at 12v my guess around 20-25cfm my load temp while folding was running right around 48-50c so the fan running flat out was helping by almost 10c it was just really noisy I think it was starting to fail making a nasty high pitched squealing sound. I should have my 60x25mm PWM fan by the end of the week so I will get that installed and let you know what kind of improvement that makes over no fan I would like to do some mild over clocking maybe the same as the factory oc cards 650 range vs 600 that I have now.

I have the new power supply but without some serious modifications its not going to fit the stock power supply is 81.5mm tall which just clears the vga connector on the back the 350 watt power supply is 100 mm tall so the only way it would work would be to make a bracket and recess it back into the case so the end of the power supply which usually connects to the back of the case is recessed back behind the vga connector approximately 30-40mm so the power supply could extend below the vga connection. After you made the bracket to adapt the power supply into its new location you could cut the back of the case to make easy access to plug the power cord in and access the switch but you would also want to enclose the bracket sides so that nothing could fall into the case and to prevent unwanted air leaks changing the ventilation pattern within the shuttle. There is enough room at the other end of the power supply to do that and after you set it back to clear the vga socket there is enough height clearance for the rest of the components. A am just not that good with fabrication to create that kind of bracket but I have not given up I am going to try to a couple of people I know who are good with sheet metal fabrication about creating a sleeve for to do that also there is no way to attach the bracket/sleeve across the bottom but it could rest on the vga connector for some support also there is no way to support it on the side next to the ice except at the upper corner and bottom corner support and attachment across the top and down the case side is not a problem.  I have not given up on the idea its just going to take some thought and time to pull off will not be a simple dremel mod.

double post could not delete if a mod would like to delete please feel free.

Shadowtester:
Hey buddy post some pics of your mod  or link me to your thread.   I have been doing alto of school work recently haha havne't had time to mod more. I'm waiting for my thermaltake 450w express 5.25 inch power supply to come in.  Basicly i'll have to take out my optical drive.  it has a max output load of 550W  so that plus my 250W  i shoudl be able to run almost any card.  I hope peopel look at this thread before they decide to cut up their beautiful case hahah.

[Shadowtester]

So far the only modifications I have done was the addition of the 8800gt which looks almost identical to yours except for the different memory and custom L&H video memory heat sinks which do a great job. The other modification I have done was previously when I have my C2Quad in the shuttle I had cut the fan shroud in half and extended it to be able to use a SanAce 92x32mm fan and then I cut the honey comb guard out of the back panel and mounted a second SanAce 92x32mm fan with a wire fan grill to the outside in a push pull arrangement expelling air out the back. Both of those fans are connected together and running on 7vdc which is pretty quiet and they move a lot of air. I also had changed my north bridge heat sink to a enoztech round forged copper one with a 40x10mm fan and I had changed the mosfet heat sinks to enoztech forged copper individual heat sinks as will being help on with arctic silver adhesive. So the only externally visible modification is the ICE fan mod. When I tackle the power supply modification I will try to get my hands on a digital camera so that I can post some pictures.

[Shadowtester]

Well I have been playing around with some mock up trying to make the bigger 350 watt power supply work and I think I will have to throw in the towel so to speak. It is possible but its going to take a major amount of modifications to work and I am concerned as to how it will effect the air flow/cooling of the mosfets as the bottom of the power supply will only be a few mm above the top of the heat sinks and in general everything will be even tighter to get shoe horned into the SG33G5. I think if your going to do a power supply upgrade on the SG33G5 your best option would be the Sparkle 270watt or the Shuttle PC50 300 watt depending on what you feel like spending and what your needs are. On a side note I think I am at the limits of what the stock shuttle power supply is capable of with my 2 7vdc 92x32mm SanAce fans and my 40x10mm fan along with the DVDrw, 500gb hdd, E8400,and 8800gt. When I try to over clock the E8400 very strange things start to occur such as not power up after its been running for a while and try a reboot without letting it cool down and unplugging the main power cord. Like wise if you try to boost the voltage even with increasing the bus speed it get less stable with out a power meter I can not verify but I bet I am maxing out my stock power supply as it stands. I think I am going to upgrade to the 300 watt PC50 I know it cost about twice what the Sparkle 270watt but you also get 30 more watts.
