accelero S1 rev2 on ati 4870

[mentalcrisis00]

Hey all

I have a sapphire 512MB 4870, it has the black heatpipe fan that the new ones have. The stock heatsink is pretty good, allows the gpu to run at 44c idle and 50 load on automatic however at load it revs up to 3000rpm which is very loud. I manually set the fan to 45% which brings it to 1800rpm all the time and is quiet but it runs at 48c idle and 68c load which also heats the rest of my system up.

I just set up a new pc for my nephew which has an 8800gt with the accelero S1 cooler, I only have 1 case fan on it and it's near the hard drive rack blowing air directly into the video card. I have a 120mm heatsink which blows air out the back of the case and it seems to work well. I was wondering if it would improve my noise levels and temps if I installed the accelero S1 rev2 on my 4870 or if I'm better off just using the stock cooler?

That stock sapphire heatsink is a very efficient one. It spits some air inside the case, but nothing to be scared about. Maybe work more at your case ventilation. 68 C is great, since you aren't overclocking either. Forget about the S1, since it will heat up your case further.

It does make more sense to have a gpu sink that blows most of the air out the back. I had a 120mm intake fan but it blew barely any air, as I saw it was only blowing more dust inside the case. My case is rather large so maybe having an intake fan that is closer to the card would help and then it could blow across the northbridge heatsink as well. My northbridge is passive so it gets up to 50c which isn't all that hot either i guess. I'm not really concerned about it as I know the quieter you get the more heat is produced because the fans run at lower rpm. A few months ago I had this system overclocked but it just got too loud with the auto fan controls.

Anyhow thanks for the tip, I'll see if I can't find a more efficient fan/ventilation design.
