Is my H50 working properly?

[Synomenon]

Got the ST45SF PSU today. Here's the system now:

Just turned the system on so I'll update later with temps..

Funny thing is, cable routing and organization is neater with this PSU vs. the modular one I just removed. Not happy though with how loud this new PSU is vs. the ST75F-P.

Ok, after an hour and a half of running w/ all cores (all 8 threads) at 100 percent, temps. shown by Everest:

Core 1: 56C (5C lower)
Core 2: 53C (6C lower)
Core 3: 56C (5C lower)
Core 4: 53C (6C lower)

The radiator feels just as hot as it was when everything was squished together when I had the ST75F-P.

The room's temperature is also lower since we've turned the AC on. I also used the stock / preinstalled Shin-Etsu compound on the H50 this time since it's supposed to be better.

Not much of a difference. I think I'll return the ST45SF and keep my ST75F-P.
