Question

Jetway NC9B-HM67 Motherboard Heat Sink is Bad

by meeramatters / June 20, 2012 9:20 AM PDT

I recently bought a Jetway NC9B-HM67 Motherboard and tested it using Prime95's test for CPU temperature. Within 5 minutes running on a single core, cpu temp was at 100 C and was throttling the clock speed to keep the temp from increasing anymore.

I think the problems I am experiencing are due to the crappy aluminum heat sink the motherboard shipped with which unfortunately is a custom heat sink for a G2 socket since there are capacitors that surround the cpu and prevent it from using a standard G2 heat sink.

Has anyone found a copper heat sink that is compatible with this motherboard?

There's more to this than the heat sink.

I've lost count of the times I found no heat sink compound, the fan not running and the machine in a "box" with little airflow.

There are also other issues such as the wrong BIOS or such. Given the issues I've encountered over the years I rarely find it to be the bad heatsink.

As to your question, if I wanted a copper heatsink and it needed a little millwork I'd use the usual black sharpie to mark what I want gone then off to the dungeon to mill it to my liking.

Just maybe, it never fully seated, even though it latched or screwed down. Find another heatsink, there are so many to choose from via online vendors. Just be sure its 100% compatible to your setup. You can also return that supplied heatsink, it maybe the wrong one, your vendor could have erred, at least check it out. I assume you did all the proper mounting of the heatsink??? I have found non-removal of paste pad covering, reverse mounting, angled mounting, too much paste, etc.. While Robert maybe right for "custom fitting" to make things work, it just doesn't bode well to have to resort to do this.
