Cooling VRAM?

[simbady]

Hi, Recently I received my replacement 4870 via warranty. I received a version of the card with a different cooler, I believe the cooler to be a newer version but not 100% sure.
Anyway, this cooler doesn't cool the VRAM directly like the old one did, using white sticky pads, this cooler just blows air over the chips.
I want to overclock my card but obviously don't want to cook the VRAM.
So do I need to find a better way to cool the VRAM or is VRAM cooling not a big issue?

Edit :


Just before I removed the awful stock thermal gunk, shaved of 7C with MX2 :O

You should be fine .. Getting a higher clock on the GPU will result in a better performance increase anyways

If you are worried about the ram chips then just get some Zalman ramsinks.

Anubis386, your siggy is way to big. Change it before a mod deletes it. 4 lines of text max.

VRAM cooling, 100% not needed, it just doesn't need it, yeah if you voltmod the card or have one of the very very very very few cards that allow memory voltage adjustment, gddr4 ran kinda hot, well the very first itterations of it, but in general for the past 15 years there hasn't been any graphics memory that has required cooling and more often than not most system memory hasn't required any cooling either.

Not to mention that the thick thick useless heat transfer pads most gpu use to connect the memory to the whole cover block do as much to insulate the memory as conduct the heat away its a bit daft.

No it does'nt. I only see 4.

***Edit*** Now it's gone to 5!! How did that happen? It's been 4 for months.

Fixed. Can't see why it changed to four lines though.

Will have to test mine next time I turn my machine off. Dont fancy poking my finger in now (ooo, err). They must have got hot enough to 'weld' the cpu thermal paste hard on my 5850 as I only use Arctic silver to attach them and not transfer pads. Have to be careful not to knock them off when putting the card in the machine for the first time when only using thermal paste to attach.

Those pads are as bad as you say they are, but the ram sinks still got warm on my old 4850. That was GDDR3 though.
