It's been up and running for awhile now but the cooler just isn't doing the job. Coolermaster sent a "alternate hold down clip" today. So OH JOY, I get to take it all apart again. They should just include the clip in the original package, but no, you have to find out that the original clip does not hold the cooler securely to the motherboard and then you have to talk to customer service and wait a week to get the clip.
