VRM sinks for HD7970?

post #1 of 7
Thread Starter 
Hi guys. I'm going to be modding a closed loop cooler on my 7970's. I was wondering whether there are VRM heatsinks for the 7970's vrms sold separately?

If there are could someone link me please?

I'd prefer to buy from amazon.com and there are a few heatsinks there but they are mainly for ram chips, would they still work? (I'm worried because the vrms are smaller).

I will be actively cooling vrms with side fans but I plan to overclock for acceptable frame rates in eyefinity so I'll be pushing around 1.2v. Thanks!

yes, ram chip coolers would still work as long as there is sufficient space, i used the zalmann (i think) blue aluminum ones

Yea I was looking at those but would they be conductive (if I use one sink for say 2-3 vrms)?

These right?

they have non conductive thermal tape on them, besides they shouldn't be touching the transistor leads. so yes they are right, my friend has them on his 4 phases asus 775 boards they work well.

Thanks!

One last question, is it okay if I leave half of them coming off (they are quiet a bit wider than the vrms) or would I have to cut them? and can they be removed?
