How I dropped my GTX 260 load temps by 25 Degrees. - UPDATE - Page 41

post #401 of 425
How thin would the fan need to be to fit in adjacent slots? I believe this can be done on the 470 also, but I have only a few mm clearance between the cards. lol Is there a fan less than 12mm thick?

hmmm...here is a 70x10mm

So i am Wanting to do this mod. I picked up the spare fan. Now, Why do i have to remove the heat sink from the from the PCB? Can't I just pull off the fan shroud and strap the new fan directly to the heat sink as shown in the op pics?
Or am i missing a vital concept here. I just don't have any extra thermal paste at the moment and am wanting to do this mod right now. So without the thermal paste I can't take heat sink off?
Advice or help please?

In order to take the shroud off, you need to take the heatsink off.

You could take the heatsink off without extra thermal paste, But just replacing the thermal paste with good stuff with drop your temperatures somewhat significantly.

Ok. Man, you've inspired me on this. So thank you!
It's my variant of stock cooler remake.

I've removed the stock turbine because it's useless after cover removing and added another one 80mm fan instead for additional cooling of the GFX VRM.
Didn't worked though. Temps are the same, 53-54 at idle and above 80 at load. I've tried with 2 fans and stock turbine and had the same results. Had the same with stock cooler (not changed) from the start. Don't know, maybe there is something wrong with my GFX and maybe the stock cooler is defected from the start (heat pipes or foot defect)...
But maybe this will work for someone. You can try and post your results.
Cheers!

I thought that the whole idea behind the shroud was to blow the heat out the back of the case (where you connect your cables to the card) and by doing this doesn't it just blow the hot air into your case? It looks like a great idea but I figured I would give you some food for thought. I'm running a GTX 480 (which I don't need to tell you that its a SUPER HOT card (temp and just in general) and if I was to do that I would be affraid of basically blowing the hot air from my card to the intake of my CPU cooler. But please correct me if I'm wrong on this. I might actually do this (or something similar because it wouldn't work exactly the same way since the cards are different) to my MSI GTX 260 Twin Frozr because I have a couple of extra fans laying around. But I only want to do it if in fact it doesn't just blow the hot air from the GPU into my case.

That looks like it might actually work. Now if only you could rig up some sort of shroud to funnel the hot air out the back then it would be perfect and would prove my last post wrong.

why not just replace the stock blower with a fan that doesn't suck... also, positive case pressure is a must with these coolers...
