The Benifits of Decent Cooling on a 8800GT (Accelero S1)

Here's mine easy to install aren't they took me about 30 minutes
this is with an 800 rpm scythe fan taken from a kama bay i replaced the kama bay one with a yate loon silent eagle.
46c load after 10 mins on an 800rpm 120mm fan in a toasty room pretty damn good if you ask me.

ok so I ordered a thermalright

Ordered a thermalright, I have an accelero s1 and get decent temps but I've been paranoid about the voltage regulators, my question is, I currently have a fan blowing across the card towards a case exhaust fan

|<-card--| where the <- is airflow and the | are fans... so essentially the card is passively cooled but with good airflow. I'm gonna change to the thermalright heatsinks because they are better quality and cover the mosfet regulators etc etc. But what is better for cooling the actual gpu, the accelero is bigger I think, which main cooler should I use for the gpu?
 
erm just stick heatsinks on the voltage regulators ? why order a whole new cooler ? just buy some swiftech mc21 and akasa thermal adhesive or use arctic silver and superglue on 2 corners of a heatsink.If you want a pro job i'd use
accelero with 120mm fan cable tied
swiftech mc21 mosfets
Enzotech BCC9 Low profile ramsinks
according to arctic coolings site
The card doesn't need voltage regulator heat sinks to operate. We tested that the card just ran flawlessly without voltage regulator heat sinks.

is it bad to change clock speeds a lot?

I have 2 profiles; stock and crysis speeds (720/1800/1980) and I always change them if I go ingame. can this damage my sweet little 8800gt?

My accelero only cost me a tenner, don't mind splurging a bit extra to get some nicely fitted sinks rather than bodging some on, can't be arsed sourcing that stuff, I'll have to take the accelero off to fit the heatsinks on anyway so which should I put back, the thermalright or accellero? I needed other things from ocuk and I just got paid, I'm being so anal about this I know but I'm a perfectionist with this crap!

Of course they'll say that if they dont include any, why do you think nvidia couple the heatsink to the regulators?
 
I think its better to be safe guys, might as well get some kind of heatsink on there, theres some small packs you can get for like a fiver which would probably fit, though I'm being super anal and getting the thermalright cooler to get the heatsinks lmao
 
Really happy with this cooler, getting 31c web surfing temps, on my BFG 8800 GT OC2. Fitted with a 120mm scythe 1200rpm fan, pritty much silent

Well, actually Gigabyte are bringing out 8800GT with a Zalman cooler (looking like VFxyz), judging by the pictures I saw there are no heatsinks used whatsoever...
 
Hi all, great thread, got some answers to some questions I had about this method of cooling...

Regarding the fitment of heatsinks to the regulators, can anyone tell me whether the cooling heatsink devices at, and underneath, marker 9 in this picture below are required?

Obviously the voltage regs around the main chip will take up the 8 'sinks you get in a pack and wondered if I could get away with just fitting them on those regs and avoiding buying another pack and fitting extra ones around marker 9.
 
Voltage regulators? Dude, those things around the GPU are the ram-modules. The components marked with 9 are the mosfets, and there's a slight controversy surrounding the issue of whether those should be treated to heatsinks as well or whether sufficient case-cooling is enough. I'd take the sink-route.
 
He knows they are ram that pic is taken from someone covering every area of the card and analyzing the heat.
 
I read this thread a while ago and recently got round to installing an S1 on my XFX 8800GT.

I'm quite literally amazed at the results. I'm running the card at 720 / 2020, so a fairly big overclock.

BEFORE:

Idle: 65
Load: 75-80 (kept at this level by fan speed going up to 100% and deafening me.)

AFTER:
(with Antec 120mm fan, silent)

Idle: 36
Load: 45 max.

My case temp has dropped so much as well. And I can't believe this is all done silently!

Well worth the money, very pleased.

(In addition, I had no issues with the RAM sinks sticking at all, I cleaned them thoroughly with ArctiClean which I think has helped immensely)

Was this clock before or after the new heatsink? Were you able to increase your clocks after installation?
 
Stable at 725/1758/2000.

But was unimpressed with additional performance - scaled back to standard speeds.

Best I got core to was 740 with shaders increased accordingly.Memory I do not wish to push too hard , have read about too many failures.

For me it was the improvemnts in temps and noise levels that really appealed and the cooler has performed even better than hoped:D
