First of all, use RealTemp to monitor the cores DTS (core temp): then, how much high your ambient temp is? Which thermal paste did you use?
Hi QFS,

RealTemp is reporting similar #s to HWMonitor for each individual core.
Ambient Temp is 22C @ 33% humidity and I'm using ARCTIC MX-4 thermal compound.

I'm going to report back after a bit more testing as I was reviewing the SPCR reviews and it looks like I was running Prime95 with the different options compared to the review standard. I was using small FFTs instead of large FFTs. I'm going to test again and report back.

Going to also try offset undervolting to see if it makes much of a difference.

Thanks,

OK, I think I'm done tinkering and I'm happy with my current temps after undervolting the 4690k. Tested stable with Prime95 28.7 (Blend) and Furmark 1.17.0.0 Burn-in /w Post-FX for 24h.

I didn't hardcode the fan speed/voltage to normalize the results, but you can still see the improvement.

Ambient Temp: 22C
Ambient Humidity: 33%

Software:
HWMonitor 1.28.0
Prime95 v28.7 build 1

Stock Voltage:
Idle Voltage: 0.720V
Ran Prime95 Small FFTs for 5m
Load Voltage: 1.090V
Package Temp (hottest core): 62-65C
CPU Fan RPM: 1011-1040RPM

-0.113 Core Voltage Offset:
Idle Voltage: 0.608V
Ran Prime95 Small FFTs for 5m
Load Voltage: 0.983V
Package Temp (hottest core): 55-58C
CPU Fan RPM: 817-833RPM

Hi guys, I read the review of this cooler and I was asking myself if it can be a good choice for my new rig:

I7 5820K
MSI X99A SLI KRAIT
16GB DDR4

I would like to overclock to 4.3-4.5Ghz but my principal concern is noise. Is it the best I can get? I will switch tha pre installed fan to the exhaust part of the heatsink and put a NB eLoop B12-2 in the front as intake. Is there any problem? Will let me reach the oc I want and still be quiet? (in idle I mean, not in full load where I don't care beacuse I'll have headphones)

For that heat load, the Ninja 4 is probably better.
1080p Gaming build: i5-4670K, Mugen 4, Asrock Z97 Anniversary, MSI GTX 1660 Gaming X, 8GB 1866 RAM, Samsung 860 Evo 500GB, Crucial MX100 256GB, WD Red 2TB, Samsung DVD burner, Fractal Define R4, Antec True Quiet 140 (2 front + rear) case fans, Seasonic SSR-550FX. 35W idle, 45-55W video streaming, 170-200W WoW, 318W stress test (Prime95 + Furmark)
