I just upgraded (or so I thought) from a trusty Hyper 212+ to the Phanteks PH-TC14CS BL (the blue one). In my original setup I had My Hyper 212+ on a 3 way PWM splitter, which ran three Blademaster 120 Fans, 1 on the front and 2 on the Hyper 212+ in push/pull. On the back I have one 120mm fan, which was a Cooler master Excalibur, which seemed to always hover right around 1400 RPM. With that setup, running the Folding@home SMP client, all 12 threads, my highest CPU hovered at around 65~67C at the worst. BTW - All temps are based on Core 1, for consistency.
So I got the Phanteks PH-TC14CS BL... Installed it, and the temps are actually WORSE. I have it running at 1200 RPM continuous (which is a little louder than I'd like). I left two of the Blademaster 120's on the PWM splitter and have one on the back and one on the front. They now run at close to 1550~1650 RPM ALL the time under load, making it louder than ever, while the temps are now 67~70C (even with the side of the case open).
What gives? This thing was $80! The $30 Hyper 212+ did a better job for cheaper from what I can tell. Most reviews showed the Phanteks idling at 30C, and the best I can get is around 40. I even re-seated it and used different Thermal compound (originally used the stuff it came with, this time I used AS5).
Any ideas? I'm about to return the damn thing and go back to my Hyper 212+. The main reason I got the Phanteks was being a downdraft cooler, I figured it would help to cool the VRM... Which reminds me, how important is VRM cooling on LGA 2011? I can't imagine the Motherboard manufacturers would have made motherboards that couldn't function without special provisions...
