Update: Got it today and wrestled it in. Early results are temps 8 degrees lower at idle and 12-15 lower at load.
With STOCK hs/f my temps were:
tcase: 31 idle, 57 load
cores: 39 idle, 64 load
(Load = 10 minutes of Orthos Small FFT's at Priority 9)
Tonight with the Ultima 90 and a Panaflo 92 fan:
tcase: 23 idle, 45 load
cores: 31 idle, 49 load
I may work back thru the calibration steps to confirm, but the temps from speedfan for the cores DID match coretempbeta's readings. Ambient in both cases is about 24.
I am much happier with a 49 at load than a 64! Though still seems high to me considering temps others post.
I suppose my next options are to either 1) try the Scythe 120 fan I also ordered instead of the Panaflo or 2) lap the hs and cpu (but I don't think I'm ready for that).
I may also consider undervolting the vcore since I am not OC'ing and running stock speeds.
Anyway, that is where it stands currently.
