Well, the clip on my PEP66 was very easy too. The performance of that HFS was rather dissapointing IMO so...
Does this HSF allow you to o/c higher than your Taisol? Sorry, but your temps as realised on the KK266's built in thermistor aren't valid--the bead doesn't even touch the chip! :|
If the [Glaciator] is doing a better job you will be able to run at the same speed as before stable with lower voltage. This is, of course, if you're not running at the wall already!
From what I'm seeing, much beyond 1.6 GHz requires water cooling. Unless you don't mind sitting next to a pc that's about as loud as a vacuum cleaner which is ridiculous!
Cheers!
