Something odd is going on here and I can't fathom it. I have switched out a Cooler Master Nepton 240M AIO cooler for a Alpenföhn Matterhorn White on a 5820K... but my temps have shot up from low 30s to high 30s/low 40s! I have re-fitted it twice, cleaning and re-applying TIM (Arctic Cooling MX-4, same as I was using before also), but no change. What is going on here? Do I have faulty cooler? I did notice there was a scuff mark on the bottom, but over to one side and I can't see that would affect temps this much! :mad::confused:

Edit: AIDA64 stress test has temps hitting around low 80s.

Do I perhaps need to wait a while for the TIM to cure and temps will settle down? Or is that a myth anyway?

Noise is fine, but I have good fans in there, Alpenfohns and Parvum F1s, so they're all pretty quiet... obviously when it ramps up you hear it, but otherwise fine. It's hard to say how it compares though because I had a reference GPU in there before and now it's the ACX cooler on the EVGA 980Ti so much quieter. I think that was probably the noisiest thing in there before. The Nepton 240M was very quiet apart from the pump making noises now and again. I have also swapped the PSU out so that's another factor which is making any noise comparison very difficult.

All I have to go on is this strange temp increase, although from what I'm reading high 30's/low 40's isn't BAD for a 5820k, it's just not great. Maybe the Nepton was just better than I realised lol! I've only swapped it because I'm making the system for my brother and he didn't want the risk of an AIO leaking.

I know it is hot now, which could be a factor, but I looked at it earlier today (before making the swap) and it was still around the low 30's. Cooling should actually be better now in the case, as I took out the Nepton from up front and added x2 140mm Alpenfohn Wing Boost fans on intake.
 
I did expect it to be a bit worse, but was slightly surprised at the amount. That said, it is AWFULLY hot right now, so things may settle. As mentioned, the only reason I changed it was because it's a build for my brother who doesn't want an AIO... I did explain it would cool better but he just doesn't want the risk of leaking or damage, especially as he has kids running about the place.
