VRM/Mosfet Cooling

[Nevakonaza]

Do you guys reckon those little heatsinks you can buy will be enough to cool these Mosfets and VRMs?



They totally switched them around on this card so that cooler does not provide any Mosfet/VRM cooling at all.

Ive noticed there is actually holes on the PCB to have one of those cooling heatsinks with the plastic push on pin which would be more ideal as it wouldnt ever fall off but cant seem to find them,this is what i mean.



Whats your suggestions guys? i really would love to run this cooler.

cheers!

Appreciate your replies guys

This is the solution ive come up with,i hope it will be enough cooling,most likely going to mount a fan somehow blowing air up at these heatsinks.





Think this will be okay?

Hope it will be enough,i was trying to find a thicker heatsink but nothing really suitable size wise that i could just mount on without loads of cutting and messing about etc,as for the chokes i read somewhere else they dont really need any sinks on them but i noticed on my cooler they had cooled those with a thermal strip across them aswel so thought why not i have spare heatsinks just to be on the safe side.

Well card is totally stable no problems at all,ive benchmarked,gamed and not one issue,idle temps are around 21 to 25c depending on room temp,under load 45 to 50c.

on the OG cooler load temps would be about 70c+

Those little black memory heatsinks are crap,fell off even before i got to put the card in my system the rest just came off with a little touch,not good overclockers i wouldn't stock these.

You cleand the chips with alcohol before sticking them on right? The stock pads can have a wax on them.
Personly I use thermal glue

Yeah,i used IPA to clean them then let it dry before putting them on,At first the appeared to stick well and i thought all was good until one fell off, the other went slanted like it was about to fall off then litreraly just a little touch with my finger on another it fell off,so they was all taken off didnt want one dropping off while it was on,So the ram chips are bare but thats fine i think as they got airflow going over them all.

I have never had a problem with them. The key to getting them to stick is to thoroughly clean the surface of the chips with IPA to remove the residue from the stock cooler. I have used Akasa Thermal Tape with those little ramsinks and much bigger and heavier copper heatsinks and have never had any fall off as long as I cleaned the surface properly.

I used Akasa thermal tape to mount those heatsinks and theyre solid,much better than whatever it is they used on those little black memory heatsinks,Its not a huge deal i can just get off the stuff they put on it then put my own akasa thermal tape on instead.

So is your VRM currently bare?

:: edit : a lot later... ::

D'oh, misread. It's the RAM heatsinks, not the VRM. That's fine, thought you went bare on the VRM was all.

Yeah i wouldnt have ran if the VRM was bare

Hey,Oh iirc i wasn't using it like that for too long maybe a month or so then i upgraded to another card anyway to put it all back to stock and sold the G12.

The difference in GPU temp was crazy, Well worth it!
Would i want to have the little cooling on the VRMS/MOSFETS for a permanent solution, No not really.

You'd be better trying to get a proper water block that covers the entire card..this will defiantly be my intention for if i do a water-cooled build at some point in the future
