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

they will have higher voltage, and or better ram chips.

apparently most GT's come with quimbonda? chips rated at 1000mhz (2000mhz ddr) but are set to run at 900mhz, giving 1800...
 
The ramsink issue is absolutely interesting, i'm looking at the possibility of passively cooling my GT cause it really makes a lot of noise, but i have on experience with putting on ramsinks or anything. Are ramsinks only a bad idea if you have the fan on the cooler? Cause i'd like to cool it completely passively.

Also i'm pretty sure that i'm hitting a voltagewall, so i doubt it would really help my overclock. Still i'm thinking of getting 2-3 years out of this card, i'll give it to my brother very soon, so i'd prefer for it to work in his rig for a couple of years too :)

Yes that's my experience as well. I believe the qimonda ram was designed to run at 1000mhz but simply couldn't do it with the voltage/temperatures the GT runs on. I can't get my memory over 1000mhz, actually on 985 and that's the maximum stable.
 
It was cold this morning. Idle temp was 32 (after 10mins surfing) and load was 42 (after 20mins ATItool):D.

Case temps should not be affected by the Accelero because both it and the stock coolers disipate heat inside the case. The same ammount of Watts (heat) are expelled into the case - the S1 just does it quicker and more effeiciently.

I remember I had some old Kingston BH5 ram that overclocked better once the heatspreaders were taken off. I think so long as case airflow is good you do not need spreaders on 8800GT ram or voltage regulators. If I wedge my pinky betwen the S1 and GC, the ram feels hot but not massively so.

I have now backed everything down to 720/1720/2000 for longevity. At these speeds it slaughters my old 8800GTS 640 (oc'd to 1650/1620/2000), and will beat stock or moderately overclocked GTX's. If I fed the GPU more volts it would probably hit 800 with this cooler. Stock load volts on my board show 1.03v. I would love to mod it to 1.2ish but my soldering is pants and there is a 99% chance I'd kill the card.

Just wondering - those people with noisy 8800GTs - are you running overclocked versions? Mine's a Leadtek at stock speeds with stock cooler and I can barely hear it, even in 3d games.

Mine is the BFG OC version, but it was silent until 8 or 9 hours ago.
Now the slight rattling goes away once I speed up the fan to 100% and then
lower it, I wonder if its touching something?

I might take it apart and see if I can see what the problem is.
 
Shocking really that Nvidia went with this type of crap stock cooler just to have a single slot design, I wonder how the stock cooler of a 8800GTS/GTX would do on the card.

Clearly a 8800GT is thermally limited and it isn't even summer.
 
I think I might buy it also, though I heard a lot of bad things about the thermal paste not holding the cooler or the ram coolers.

Is the fan you put on the S1 important? and can that fan just be plugged into my mobo?

also, the S1 + extra fan = 3 slots in total?
 
maybe someone could try what i have done, which is stick an antec exhaust blower fan right next to the accelero s1 on my x1950pro agp. it pulls the warm air outside the case so you get some good benefits of lower case temps too.

here is a pic of how i have it done:

be warned though, the whole thing ends up taking 4 slots including the gfx card. but if you got slots to spare then why not?
 
Just fit a 12cm fan underneath, use the holes on the fan through the alu strips on the S1. Quieter than the turbo module, and if you have a 12cm lying around...free.
Probably not needed on cooler cards, but on ovens probably worthwhile. You don't need much airflow, just enough so hot air is removed quicker around the fins.
 
You can even fit 2x12cm fans side by side if you really want to drop temps. That would cool GPU/Ram/Voltage Regs nicely.

If yoa add additional fans to the S1, it will take up 3 slots. Not a problem for me but might be for some.
 
I got an S1 and a load of ram sinks for next to nothing off a certain auction site, going to couple my 2 yate loons up onto the beast. However i have been waiitng 16 days now for my 8800 gt to arrive and its still not here.

Must admit, my case needs a serious upgrade to helpwith air flow... i can't keep cutting holes in this one! lol
