Windows 10: Back to Liquid Cooling for CPU

I had initially installed a Deepcool "Captain 120 EX" liquid cooler on my new built with an i7 6700K CPU. I got concerned about the liquid and removed it and installed a Noctua NH14S with second fan. I need a "quiet" PC as its used as my recording studio system. However, the CPU is running 10 to 15 degrees C hotter at idle or minimum CPU use and much hotter under load and I don't like that. Speeding up the CPU cooler fans don't do much. So next week, when I have a chance to do it, I'm going to reinstall the Captain 120 EX. I'll chance liquid leakage for the better cooling. Both coolers have quiet fans so that is not an issue.

Noctua has a good reputation. I used Arctic Silver compound when I installed the Noctua. I've been using CPUID HWMonitor and Core Temp to check temperatures. Both report about the same. Right now, at almost idle I'm seeing upper 30's C for the CPU cores. With the liquid cooling it would be upper 20's.

I'm still waiting for Cooler Master to send a kit for AM4 to install my Nepton 140XL, it's so much better than my Mugen3 which is also enormous air cooler. Nepton brought me at least 200MHz of OC over Mugen. In mean time I micro polished contact surface so it will be even better. I mounted radiator and fans to the outside back of the case and there's so much more space inside.

The Noctua cooler almost does not fit in my BeQuiet Silent Base 600 case. After I installed it I was concerned with space. I just barely get the side panel on. With the liquid cooler and the radiator and fan there is plenty of room.

Just a little tip on Arctic Silver, buy some Arctic MX-4 and use that next time, its Much Better then the Arctic Silver compound.

Mike, that is an often debated subject. There are a lot of people who disagree with you and some who do agree. Arctic Silver just takes a long time to 'cure', over 200 hours by many accounts. Personally I always use Noctua NT-H1. But, I digress. Lets not turn Fireberd's thread into a which Thermal paste is best thread.
