I used ground water cooling. Water force:0.1Mpa, September run to now.

Noob, if you use well water, dont do direct heat exchanging. You will fuck up your waterblock and contaminate the water vein.
Do it right and do non direct heat exchanging. You can keep your waterblook alot longer with proper coolant too.

Run three consecutive months, No problem, As long as no copper, Only plastic and aluminum, is ok

I like your setup - very clever use of water, and (unlike seriouscoins concern) isnt going to contaminate anything, other than perhaps EXTREMELY limited traces of aluminum or PVC being put into the water.

however, you could see some calcium or lime scaling of the C1 heatsinks over a long period of time - though it would likely take 6+ months to build up noticably.

what temperature is the inlet/outlet, and do you use the hot water created for useful purpose, or just soaking back into the ground?
