Worth getting an Accelero for my GTX 285?

[alexp999]

I'd been having some strange lock ups recently on my OC'd GTX 285 and from what I can tell, temps were the issue, back when I first got it and OC'd it, ambient temps were 5-10*C cooler, now under load its running about 7*C hotter. This has caused me to reduce my OC to:

725 / 1512 / 1350

And thats at 100% fan, it passes 1 hr of OCCT. Now I know shaders biggest hate is heat, and when i kept temps below 70*C on my GTX 260 I was able to get another 30 MHz out of them.

So I'm looking at going aftermarket on my GTX 285 so that temps arent holding back the OC, atm, on 100% fan, temps top out at 75*C with 25*C ambient.

Now I know the accelero is capable of knocking around 25*C off GPU temps, but what Im worried about is all the other temps.

I didnt touch the accelero with my GTX 260 due to the terrible VRM temps, however upon reapplying the TIM to my GTX 285 earlier today, I noticed that the main VRM area is not in any contact with the cooler.

But what gets me is that Artic Cooling says its fine to run the memory and VRM without sinks provided the fan is on 80% or higher.

I'd like to know if anyone on TPU is running an Accelero GTX 280 on a GTX 285 as per the instructions and if everything seems to operate okay.

Let me know your thoughts

I say no. It may help cool the GPU more efficiently but the other hot chips on the card are going to suffer, and if you are going to try to cool them as efficiently as the stock cooler you're going to end up adding more fans, thus making it louder than the stock cooler. Nvidia coolers are designed very well. Of course OCCT is going to get your card very hot! There is no real world application that will come close to that.

Yeah it does get it really hot, but I usually find that 1hr @ 75*C is the same as a long gaming session at 68*C

If I'm OCCT stable I;m game stable. If games start playing up OCCT usually throws up errors.

Just not sure on the capabilites of the cooler, whether air is just enough, the stock GTX 285 cooler only makes contact with RAM, GPU, NIVO and about 3 other places, not the main VRM

EDIT:

That said, all the factory cards that have the accelero already on em dont have ram sinks or vrm sinks and overclock like troopers

You dont even need to overclock your card that much for gaming!!
The only time i push mine is when i run 3dmark benches!!
Graphics cards will perform better at a mild overclock than pushing them to the edge while gaming!!
So turn your fan up and leave your clocks around stock for gaming!!
No need for a cooler!!

Thats so not true, I noticed a difference between clocks for gaming, sure not on older games, but on most of the recent ones I do, it can make the difference between laggy and smooth framerate.

I cant see the point in benches if they are not what you use for gaming, my PC is a gaming PC, I want the max out of it I can get.
