226W cooling gfx core and ram?

[drunkenmaster]

Just an idea, mainly as i have a 226W tec, a 172W tec would be a pain cos of voltage, but not too bad, but would still need to buy.

ANyway, something like a cold plate making contact with all ram chips and core, a maze 4.1 basically over where the gpu is, Would a 226W pull enough power to draw heat through the cold plate from ram to tec? or not really useful enough?

If i did then di-elec grease all through area, very thin neoprene between coldplate and card up to ram and gfx. then neoprene all around the cold plate, on the backside and around block base area sealing in tec.

ANyway, any chance that would work, and maybe work well?

I don't think it's really even useful to TEC cool the ramchips, and I doubt much of the cold would go through the coldplate out that far.

hmm, yeah, i' m not really sure tbh either. its just ickle ram sinks seem crap, and there aren't many good ones you can get really. Just thinking that if a mcp50-t is only working at aroudn 60W on average, even clocked up a gfx core would be hard pushed to use more than 120w, leaving quite a big overhead for pulling heat outta teh cold plate. Should allow for slightly safer over volting of the mem i would think, if it does cool them well.

[sandman]

well, it might also just cool the gpu core more though too.

Don't think you'll be able to overclock the mem higher with that method then cooling the gpu alone.

Personally, just stick to cooling the GPU. Small heatsinks on any memory chips atm are all you need, to put it in perspective, OPP still uses ThermalTake aluminium heatsinks cut up on his memory on his graphics cards for benching. Its the GPU that creates the real heat and needs cooling however. Best way to attach these sinks are either:

Use a small drop of super glue on the corners of each memory chip and a TIM in the middle or the chips
Use some sort of thermal epoxy for example arctic alumina although this is more difficult to remove the heatsinks if you ever need to

There are watercooling solutions that allow you to coll both GPU and Memory at the same time, theres a Gainward FX5900 that comes with it at stock, take a look here. (http://www.frozencpu.com/cgi-bin/frozencpu/ex-blc-61.html)

Just my 2 cents.

Yeah, i do think it wouldn't really give me higher overclocks than i could really get on air. But if I was doing vmods, and running near limits where it could die in jsut 2 or 3 runs of 3dmark, woudl sub zero cooling make them work a little easier and maybe give let me use slightly higher voltage.

Bha, i doubt it, i'm just bored looking for something extra to do :p

Al lthe extra cooling would give you to the memory is increased stability during 3Dmark runs and increased life of the card. For example a good transfer interface material (such as AS3) lowers the processor temperatures over a standard generic paste but does not increase your overclock, I think this would only lower temperarures, thus increasing stability and the life of your card but i do not believe it would increase your overclocks.
