CLC and AIO leaks are rare, but pumps start failingThe main concern I have is leaks. Dont want pc to get destroyed because of water hence why I don't go for a custom water cooler. If pump dies ill go get a different one and most likely will also never touch the aios again.. the cooler you posted woyld be nice not sure how much it would handle 3950x with oc
after a couple of years.
TRUE Spirit 140 Power is rated 360w TDP, the highest rating of any air cooler I know of. It uses 6x 8mm heatpipes while most others use 6mm heatpipes. 8mm heatpipes are rated about 30% higher cooling ability than 6mm heatpipes because of increased surface area and volume.
Ignore talk about availability, mount, etc. He obviously doesn't know who UK dealer is or much about product availabity. If you have any questions contact Thermalright.com and they will answer you no problem.
UK marketing is website you know about. Obviously Amazon has almost everything known to man but not always good sources to buy from.

There are no posts of mount issues or poor customer support, but there are a few about mounting fan clips being kind of a hassle to get fan mounted posted by first time Thermalright users. Easiest way is to practice mounting fan a couple of times before installing cooler. Clip one side and hold fan toward other side so clip stays in place, then clip 2nd side. Newer Thermarlight model coolers have easier to use fan clips.

Relentless,
If you want to know who Thermalright UK dealer is message me or aposolis_kt.
C700P has 198mm CPU clearance, more than enough for tallest coolers.The case is the cooler master c700p, I think there is plenty of space for a beastly cooler, but yes the ram part is the concern. Also the x570 master has the only rgb on the vrm part so that would be blocked I believe if I put the second fan on the other side.
