SG33G5, temp do I have a problem need advise.

[darkjunky]

Hello, this is my first shuttle and I'm after some advise on temps. Currently I have idle temps of (with the case off);

Mainnboard  42C
CPU            36C
CPU Core    32C
HDD           19C
GPU            44C

And at load they go upto

Mainboard  50-52C
CPU           48-50C
CPU Core   36-38C
HDD          20-22C
GPU           51-55C

These temps seem high to me? I've done everything I can think of to reduce the temps, replaced the stock thermal compound with arctic sliver 5, added a slienX 92" running at 1500rpm at the front of the case and have the stock fan running at 1300rpm. I have heatsinks on the ram and even a heatsink on the HDD. But it's still running hot and I was hoping to put the case back on at some point.

Below is my rig.

Shuttle SG33G5G
Intel Core 2 Duo E8400 LGA775 3.00GHz (1333FSB)
Kingston HyperX 4GB (2x2GB) DDR2 6400C4 800MHz Dual Channel
ATI Radeon HD 4870 Graphic Card 2gb
LG CH08LS10 Blu-Ray & DVD Player
Samsung SpinPoint F1 HD103UJ 1TB Hard Drive SATAII 7200rpm 32MB Cache

My first question... how do you have a 4870 inside a SG33G5 case?

[darkjunky]

The same way everyone else gets large cards into a SG33G5 a little bit of modding on the case, and it hangs slightly out of the case. I've cut a hole out of the side of the case and edged it with crome car edging. Looks decent enough but it was tight squeeze but it fits and runs perfectly.

Hi darkjunky,

welcome to the Forum
I think you get those temps cause of the 4870. The backside of the card can get really warm and the card is blocking airflow from one side to the other. Think this is the cause for your MB temp.
It's interesting to see that differnce between CPU and CPU Core temp.
Don't know what temps you are expecting but to me as an P2 owner those temps look good. I get up to 70°C MB temp under full load, cover closed

Hi Devellow, thanks for the post I'm glad to know you think these temps look good. But as I said this is with the case off... Can you think of anything I can do to cool the inner side of the 4870? Because your right it runs super hot and heats up the rest of the machine. I went for the Vapour-X because it's a smaller and cooler card then most others, but it still hot

70C is my bois shutdown marker the TDP for my processor is 72C.
I'd like to keep the temps below 60C if I can help it. Once I put the case on I'd imagine these temps will go up by 5-10C, but you reckon running at 60-65 at peak load will be alright?

I can do some more testing tonight with the case on, and report back. What about my PSU, do you think the fact I'm bleeding my 250w PSU dry, could be causing these temps?

Hi there

Your temps seem quite reasonable to me, especially cpu, motherboard/chipset temps in shuttles tend to reach similar temps as the cpu probably due to the limited airflow inside the case with all the hardwere in its place.

However improving your internal temps isnt that easy, G & H cases rely on the ICE fan to cool the internal components, we wont count the psu fan as its tiny (40mm) and fresh or cool air enters the case through the various grill openings, which on one sideof the case is going to be blocked by your ATI 4870, that just leaves the space in front of the psu and under psu for cool air to enter your case.

Since you have already modified the case to allow for the installation of your ATI 4870, you might aswell modify it further cutting an "L" shaped window on the psu side of the case and installing large hex mexh mesh. take a look at these photos of my modified sx48 p2 case to get an idea of what I mean.

 

Take your 2nd 92mm fan and install on the back of the case to work in a push pull configuration with your original ice fan, this will increase the airflow without increasing the noise. If you want to maximise airflow remove chrome grill from ice fan and remove the exit grill on the rear of the case ( it will also lower noise from the fans )

Shuttle use to sell optional case cover for the G series with a mesh window on either side, I supose you could get hold of one these and modify it to allow for your graphic card instalation. I have just seen one on ebay.de

Thanks alot for your insight, I've noticed in lots of other shuttles / sff they have an inlet fan in that space between the PSU and the front of the case but on the G series there is simply no space perhaps 50mm which is mostly blocked by power cables and the HDD drop-in cage and the RAM.

The 92mm fan I've mounted in the front of the case is able to draw air in from the floppy bay flap and pass cool air over the Blu-ray, HDD and CPU which has helped cool the temps. But you reckon this will work better with a push / pull setup, I will try it tonight, but the data I've seen today shows 0.5-1C improves with push / pull. I will likely replace the stock fan eitherway since it is noisey even at 1300 rpm where as a SilenX IXTREMA at 1800 rpm is only 14 dBA.

I've already removed the crome grill from the rear of case which again did improve temps and I'll consider your mesh mod.

[jrturbo]

Hi there

As I said its the ICE fan which draws out the hot air, if you feel you additional fan at the front is helping, it would still be wise to add a sencond fan to the ice cooler on the outside.

Regarding replacement ICE fans, any 92mm run above 1600 rpm start to became quite audible, which is one why noctua and silenX 92mm fan runs at 1600 rpm at 12 volts, however the ICE fan is pwm controled and a noctua or silenX isnt Pwm, I personaly would sugest you got 2 decent 92mm pwm fans and run them below 1600 rpm, however you will have some cooling headroom should you need it as the fans could be made to spin faster, most 92mm pwm fans reach 2000 rpm or more.

You can use the program called speed fan to control the fans and  the temps.

You can try this. I have my SG33G5 set up with two HDDs, so the bit of breathing room for both of them was crippled, and it made a small but noticeable impact on the heat inside the case.

First off, if you don't already have it out, take out the floppy placeholder on the front of the case, under the click-on flap. cut some foam and place it there and close the flap. the flap will stick out about 1mm, but that 1mm makes a HUGE difference.

secondly, a fan on the northbridge is a must. they supply a fan connector there already, so do it. I pulled one off an older P4 shuttle's northbridge and placed it on. if you can, also replace the crud Shuttle uses for keeping that cool with AS5 or Tuniq TX-2.

now, since I had to go the extra step, I placed an 80mm fan over the left side of the drive bay bracket, as shown below. since you really don't get a lot of airflow to play with, it helps to move around what you have... and, in its current spot it can get some (SOME) of the air from outside the case from the vent holes. It made a difference for me, and keeps the memory cool to boot!

again, as has been stated, take the chrome plating off the ICE fan. I didn't for the sole reason of keeping cables from stopping it up given something might happen if I leave it unattended... but I still get a decent amount of airflow with a second 92mm fan on the back, which is NMB branded off some older PC I had.

With the case holes, if you wish not to mod it out, put some foam over them, be it glue or double-sided tape or what. Since I'm going to be getting a new case shell soon I superglued some new foam onto mine and have been giving it a patdown every three weeks... not much dust gets inside anymore and it's made a huge difference in temperatures too, because there's nothing getting in to clog up anything

so yeah, try that. this is just based off of what I've done so far though.

and here's the pic I said was down here:

this is something else I've been meaning to get to also. but, that time will come when my spare cover gets in.

Hi Sudos,

Thanks for your input on this, I'll replace my thermal compound on the north bridge tonight and order a 40mm? fan for it. Theres no space whats so ever on the left side of my case for a fan like yours mate my 4870 goes right to the very end of the case and right to very top, the power cables actaully touch the front of the case and the top of the card reached the cable tidy bit at the top. I've removed the grill and will try that trick to keep the floppy bay slightly open for the extra air intake.

I tried it last night with in push / pull with the SlienX in push and the case on and got the following results after 30mins of Intel Burn Test;

MB 55
CPU 43
CPU Core 51
GPU 48

So I'm happy with these temps but these tests were not hammering the graphics card, just testing the CPU at 100%. Also just looking at your pictures here you may benefit from some cable management I used blue cable meshing and shink wrap to tidy it all up and that helped.

I'll post some pictures of my mods later on in the week, I'd like to see a few more shots of your SG33G5 and are you still rolling with the stock 250w PSU? I've been thinking about getting a 300w or 400w since thats what I'm told I should have for this rig.

also where are you getting your spare cover from? I could do with a new cover with meshing and a new drive drop-in cage

[Sudos]

I'm getting my cover from eBay... most of the shuttle covers are interchangeable so it might be a different color... which doesn't matter. if I have any left over from my paintjob to the valve covers to my car in the garage, I have a can of high-temp neon green spraypaint that would make it look real nice.

Yeah, I'm not the best on cable management, I've tried what I have there and I can't seem to get it any better than the way it is now. if you're gonna get a 40mm fan make sure it's maglev/everlube and not ball or sleeve, they last a lot longer in the smaller fans.

your CPU temps are spot on. I'm looking at a different way for the push-pull factor to go through on mine, though. A bit back someone posted some now dead-linked pics of how to install an Intel stock fan onto the shuttle ICE cooler, to lose the shroud. As for the rest of the unit, yes, I'm still using the stock PC40. I'm a bit tight on money so it's been working for me fine. the PC50 might be better but I'm having no problems at all with this, so it's not on the top of my priority parts list. The shuttle power supplies are built for efficiency though; a 250 is about the same efficiency for power as a 350 or 400 in some cases... it also depends on where yours was manufactured. if you have an offbrand FlexATX 250 in there and not one that says Shuttle on it, those are still alright and they work but I've never trusted them. I had to install memory in a bunch of prebuilt SG31G2's that came from Germany here to the states for my father's place of work. within the month two of the power supplies died and were replaced. three months later nothing had happened but my father decieded that it would be best to switch to the brandname ones anyways... so, wasn't my call. he was actually the one that talked me into getting the G5 in the first place.  I'll take some pics now that I have it open though.

Alright, I decided to go the easy route and log into my dusty flickr account to host these... the guy I'm sharing webspace now would be mad at me if he got a lot of traffic from people looking at this forum for posted pictures.

cheers for those pictures looks create. got some nice insight into how to do a few things on mine. Is that a USB wireless card strap to your tv card?

I've seen that intel fan mod aswell but didn't like the look of it tbh.

it's not a TV card, it's a Belkin 5-port USB card. that port was loose and I got fancy with some electrical tape.

I figured some stuff out, ad where to put the wireless card, as well as found a, internal USB wire for it. so that card is as of now gone, and in its place is a gigabit card... I never liked the onboard and the one I put in is doing a lot better.  I'll put in some more pics later, as I did something else that I can't go into detail about, but when the time comes pics will be put in.

Hi Guys, just wanted to give you an update I've just got my 2nd SlienX 92" fan and I've mounted it on the back. It helped the temps a fair a bit so I've gone ahead and overclocked my CPU from 3ghz to 3.5ghz.

After 30mins of IntelBurnTest. Highest core temp was 54C but it was averaging 51C.

Below is a few pictures of my rig I'll get some more pictures and updates soon.



As you can see there isn't much space in this case and I've blocked off most of my air flow.



You can just about see my hard drive there in a copper heatsink, I only have one hdd and an empty bay because I can't spare the power or extra heat of a second. I'm also thinking about getting a SlienX 40mm fan for that northbridge.



This is my HD 4870 2gb, it takes up all of the space up and hangs out of the case a little bit. But i've cut a hole in the side of the case for it hang out of.



As you can see here the power cables are actually touching the front of the case and it takes about 10 mins of fiddling to plug them in they both have to be slid in at the same time.



This is it with the drive cage in fits in snugly.



CPU Heatsink and first fan.



Rear of the can and second fan.



Powered up and case on.

Very great theme ! i really enjoy it, thanks a lot for sharing the different step of creation, avaya certification training very interesting to know ! I completely agree with what you said. base sas certification questions I book mark it and mail all of my friends to check it.

[denzilorton22]

I have referred it very well. It would be helpful for those who have wanted to built new CPU. I think that You have putted best effort for that theme. I am sure that People would be stuck who are not awe about it. I hope that  will also make CPU myself.
