3rd party vrm heatsinks

[geoc]

I've always wondered are those dinky looking vrm heatsinks for videocard ever enough? I have a gtx260 under water right now, and I have cut the vrm section of the stock heatsink and kept it on the videocard, unfortunately the vrms are hitting 150C underload.

I have quite a few bga ramsinks and vrm heatsinks I could throw on, but I lack faith in those dinky little things keeping the vrm cool.

What are your thoughts on this matter?

They actually do work, if you can keep them stuck on. I ended up scraping off the double sided tape & using a two component adhesive.

What percentage do you mix with thermal paste? I only have ceramique left, my AS5 ran out.

You can use it as is, without mixing with thermal paste. Try experimenting, I believe that by mixing in paste you lessen the strength of the glue.

I read online that if you use pure adhesive, you can bet it will never come off (should I decide to remove it in the future). Mixing it with paste allows you to remove it in the future if you choose to while maintaining a decent amount of adhesive strength. Did you just straight glue them on?

Yes I did and they came off fairly easily when the the card was still warm. I would do some test samples to verify that.

it's epoxy , so you mix 50/50 the 2 alumina tubes
