Since the fall semester of college is upon us, I decided that my previous gaming rig was way too loud to bring to the dorms. Instead of selling the old build, I decided to move most of the components into the NZXT H440. Many reviews warn that the case isn't nearly as quiet as they'd like, but I'm quite happy with the case's performance. The noctua's are a huge improvement over the rattling corsair fans that came with the h100i and generate the only noise that can be heard from the case. I'm still running stress tests, but so far, the transition has been fairly smooth. I can't wait to start over-clocking!
I started to overclock at a mild 4.2GHz, but for several reasons including: bad airflow in the h440, possibly a bad batch of AS 5, and probably a defective h100i that I need to RMA, I was reaching temps in the high 80's during stress testing. I re-seated the clc 4 times, making sure the back plate was installed correctly and there was good contact between heatsink and cpu. I even switched to nt-h1 on the last attempt, but even then, temps went straight up to the mid 70's at load.
So, I decided to switch to air cooling and try the Cryorig R1 Ultimate. I bought a third nf-f12 and swapped out the stock NZXT case fans with noctuas to help with better intake.
The temp difference is drastic. Instead of idling at 40 like it did with the clc, my CPU stays at a cool 33. I just ran prime95 through the night and the temps fluctuated between 69-71, with the lowest being around 66.
Although my temps are not in the mid 60's like I'd hoped for, I should at least be able to reach a 4.5GHz overclock now.
The H440 is not a good case for clc like the h100i and the Cyrorig R1 Ultimate is a good air cooler that doesn't look half bad.
