Ahhhh... quiet at last!!

[Zut50]

I finally got around to doing all my quietening mods I had planned, and a few I hadn't planned (see my earlier thread!)

I switched my Noiseblocker S4 for an S3 as an ICE fan, I switched my PSU fans for the 10mm Adda replacements from Ulim8pc.co.uk, and since I had no choice I replaced my ravaged GPU fan with an Iceberq4.

However, the Iceberq4 wasn't designed for an old GeForce 3 like mine which I discovered the hard way. However I took a hacksaw to the offending protrusion (one of the tabs that hold the plastic shroud up), and replaced the 2 big aluminium heatsinks that would not accomodate the massive Iceberq, with 8 small copper ramsinks (Coolermaster ones). The ramsinks provided with the Iceberq are BGA, and theres only four of them so they were a little useless!

I also got round to buying a 10cm (4" I think) cold cathode, but there was only one in the packet. A single 4" cahode tube does not make for a spectaular display!!  Oh well; at least I can sell my old tubes that are too big now!

The whole thing is certainly alot quieter, and with the voltages to the ICE fan and the Iceberq turned to about half (on a rheobus. I dont know the speedfan equivalent) I cant hear it over some light music. YAY

I can also report, for anyone still bothered, that the LED on the Iceberq has only two settings as fan as I can tell, bright and dim (and off ofcourse, if you turn it down a little too far!). Still looks cool though

Thanks for the inspiration, and the fantastic tips everybody!

I have my ICEBERQ fan running at 1% in Speedfan on my 9800 Pro.  It's completely silent at this speed, and it's still spinning.  At 2% you start to hear some whirling(very quiet) but I prefer no sound

I noticed that you didn't mod the chipset fan, that is a very quiet fan but I started noticing it after I did all the rest of the mods.   I went with a Zalman Northbridge passive cooler, there is 2 flavours you can go with.  There is one that is blue taller one(the blue one doesn't have much clearance for the HDD bracket and cuts closer), and a wider orange one that are both effective in cooling the chipset.   Depends on which one you prefer I say you should go for it.

Ooooh, can you get away with 1% on a 9800Pro? (I assume only when its not under much load!) How fast does it spin at 1%, do you know? If it makes the light dim, then its very low! I daren't run mine at a low voltage, but if a 9800Pro can do it, then so can a puny little GF3!!

Oh, and the SB65G2 comes with a passive NB cooler anyway, as there is no onboard graphics.

I went with the Zalman blue (tall) NB cooler. I think maybe it raises surrounding air temps under the hard drives
a little more than the other version might. Its not a big deal but you might want to consider it.

AS long as you have a decent airflow, it shouldn't be a problem.  I don't notice it raising the case ambient temperature at all, that's probably because I have a 92mm fan at the back.

Well according to Speedfan it's running at 3300 RPM(most of the time it's screwed up at either 0RPM or 33400 RPM lol) even at 1% on desktop, and yes, I do get away with 1% on a 9800 Pro.  I have artic silver 5 on the ICEBERQ which is probably why it's performing so well, as for the light it's still very visible indicating that it's probably really at 10% speed of the fan rather than 1%.

What I noticed is that at 12% it's already running at full speed.  So 1% Speedfan, it's probably running at 8.3% of the full voltage/speed of the fan.

The heatsink itself is even touchable, maybe because I have a 92mm Fan at the back sucking a whole lot of air.

Is there any trouble mounting the Passive cooler? I'm looking at going for the wide orange one for the sb75g2.

Thanks

Very interesting stuff you reported there. I'm about to upgrade my Geforce4 Ti4280p to a 9800pro and mostly I've been thinking on a all the hard and complex work of re-designing a zalman passive heatsink for the gfx card. Which leads to my question, what kind of noise level does the iceberg4 pro generate? Love to hear some details on that.
Secondly, have you mounted the 80->92mm converter + fan inside the casing or at the back? Whatever your answer is, what kind of noise level and temps do you get?

Appreciate your comments.

update regarding mounting an iceberg.

is it possible to connect the iceberg fan to a motherboard connector to control it in bios? I have considered to try controlling all fans in bios to be able to run the mod config without speedfan (not having anything against first class software).

anyone of you know where a humble person like me can get my hands on an iceberg i scandinavia? (i.e. Sweden), any other European dealer would suffice too. sorry for crossposting.

keep it real

Maybe too late, but I've discovered that Sharkoon (SVC1) and Revoltec (RS002) seem to be the same beastie as the Vantec

Yea, I solved the matter by getting a Titan copper. Still no upgrade of the video card. I have had little luck when it comes to deciding which card gets me the most power for the lowest buck. Have been thinking a lot of the 9800 pro which is a good purchase these days I hear. And ofc the gigabyte passive 6800.  The gigabyte is pricier but I guess it should perform accordingly. Still im confused tho, so my geforce4 Ti card remains, silent tho with the speedfan controlled titan.

where do I get a gigabyte passive?
