VRAM safe operating temperature

[Jumpinforfred]

Hi 

I just redid all the thermal compound on my graphics card. The VRAM chip's had cooling pad's which where in a bad shape so I had to chuck them. I used a sufficient dose of thermal compound to compensate. I'm going to measure the the temps of the chip's with a laser thermometer tomorrow and I'm wondering what's the safe operating temperature for these chip's. If they are to high I will go out and get some proper thermal pads. 

Thanks

VRAM should be below 70C

So there were a very tiny pad in place of where you put paste? Like paper thin?

 

vram doesn’t always need cooling either.

Well the pad where thick enough for me to be worried. Apparently they are 2mm thick

Yea just wondering how you could fill a 2mm gap with thermal paste. Unless the thing making contact moves or flexes enough to be that close.

That's thing i'm worried about because i'm almost positive that the heat dissipation of my Vram chip's is less than optimal.

Should have left the pad on it. Until you got new ones.
