I get Coollaboratory Liquid Ultra for $8 (amazon points on card dropped it from $16ish).
I test my pk-3 delid i7, at email@example.com.
Max temp 105*C?, I had throttling on the 3rd core, the rest of the cores were like 98-99.
Then I put CLU on both die and ihs. I put a tiny drop on die, spread it, then what's the brush, i spread under ihs. You really don't need much of this stuff at all. Then I put a similarly, but slightly larger tiny drop on ihs, spread it all over.
I have max temp of 77*C. a ~30*C temp drop doesn't really sound right, especially since I tested firstname.lastname@example.org before and ran a 24 hour p95 test even on that setting with a max temp of 89*C. So I don't know what happened, I didn't reset the cooler or anything....
But I'd say I got a temp drop of ~12*C going to coollaboratory liquid ultra.
I'll post my 24/7 prime95 overclock on this cpu later. Just got a new PSU because I had a faulty one before, I'm sure this chip can do 4.9ghz if not 5+, on reasonable voltages.
