SATA drive stops being detected

[MisterEd]

I was playing GTA V, paused the game and then minimized it. I forgot about it for at least 30 minutes. I tried to access HD#2 but the computer froze. I then noticed that the CPU temperature was at about 66C.
I shut down the computer, waited a minute, and then rebooted. The computer took a long time to boot and again HD#2 was not detected. I shut down the computer for 1-2 hours. When I  booted it everything seemed normal.

I have a Corsair H60 water cooler. Since there is not the normal airflow on the motherboard could the chipset have become overheated and caused the problems with the SATA interface?

The case should provide sufficient airflow watercooler or not

maybe the watercooler is defect?
system temp (mobo) should not exceed 40 celsius or suffa

check HD temperatures too! 40C max is the ideal temp for a HDD too

I hadn't responded until now because I was waiting for the problem come back. After a week it did.

I reversed the flow on the 120mm side fan to now blow out. After three more weeks the problem with the disappearing hard drive has not returned. I think the problem may have been because I had 4 fans blowing in (2 front, 1 side, 1 rear) and only 1 blowing out (top). This caused the heat to build up inside the case. Now with 2 fans blowing out the inside temperatures (CPU, GPU & motherboard) all seem to be cooler now. For example the CPU seems to running during gameplay 45-55C while before it was 55-65C.

Don't think that the CPU should always be 40C with the water cooler. The Corsair H60 is not a high end water cooler. I realized that when I got it. I got it to keep the computer under normal conditions quiet. It does a good job of doing that.

Another thing is the game I have been running is GTA V. It stresses both the CPU and GPU more than any game I have ever had.

It's called an oven - if more intake/blower fans than suckers extracting air.

I dint say a word about CPU temperature - you can run the CPU up to max heat recommended by the manufacturer but ideally it should never exceed 60C even under full load.

System temp is motherboard hence in-case temperature. Make sure there is proper airflow through the case and temps shall be all good.
