Blizzard 1240 heatsink

Hi everyone,

I've recently bought a Blizzard DCE 1240 card.
Unfortunately it has a stupidly small and stupidly loud fan.
I want to replace it, but i just can't get it off!

Does anyone have any idea how could i remove the heatsink?

And has anyone used a "double-sided adhesive heat conductive foil" to glue on a new heatsink?

I've bought one of these:

I'm hoping it will be OK.

If you have any idea, please don't hesitate to share it :)

P.S. When the CPU is on, it's about 44 C. Is that in normal limits?

Thanks

@uGod

I'd be keen to find out if there's a solution as well. Beyond using a grinder.

Update:
I read somewhere that soaking it in a shallow bath of acetone will dissolve the thermal glue.
I'm going to give it a go.

@agami

You need to be really carefull with that. You can easily destroy card with acetone.

@utri007

But what if i just drop a drop of acetone on the glue on one side, leave it for a few minutes (hours??), then gently force the heatsink and the CPU a little bit apart, then the next side ... and the next ...

@agami

You mean a hand grinder??
Or a CNC? :D

With a CNC i could imagine it could be done, but i don't think i would try it on my card :D
