Help me replace TIM on my non-reference 5850

post #1 of 6
Thread Starter 
So my temps have gotten a little out of control because of my high overclock and since I can't accomodate an aftermarket cooler in my case, I figured why not replace stock TIM.

I'm going to buy shin etsu x23.

After I take off the heatsink, what locations require thermal paste? GPU base, VRMs, RAM? Anything else?

How much should I apply to each location?

And if I remember correctly, on the RAM chips are thick thermal pads that should not be removed. Is there a way for me to reapply GPU TIM without removing those thermal pads?

Anything else I need to know?

Thermal pads are reusable so you don't have to apply TIM there. Put a rice grain size of TIM in the center of the GPU and apply pressure evenly after placing the HSF on it.

Some of the stock tape on the card you will find is more like crushed foam. Some of the tape on the memory is very thin also. I would order a kit of tim tape that has various sizes/thickness in it, 15-20 bucks or something along with your shin etsu. Then replace the foam type tape with appropriate replacement from your kit, I'm not really sure what it is but the foam breaks down and is barely reusable. As for the shin, I put a layer on on whatever that has tape that is fairly firm. It will improve contact on the firmer tapes but not on the squishy foam type stuff.

I've never felt to need to replace the thermal tape/pads on any of my graphics cards. All you need to do is put new paste on the GPU.

I thought more TIM was required on GPUs because the base is so much larger than a CPU.
The rice grain is more traditional for CPU thermal paste applications.

The bottom post suggests against reusing the pad...

In that case I don't think my $30+ investment is worth a 3-5 degree drop in temps...

And what are your RAM and VRM temps as result of that?
Same? Worse?
