When running at high load i noticed that the liquid in my cooling unit is hotter than the CPU. Is that normal?

Yes, it is designed to take the heat away from your CPU.

It's just because I changed from an intel cpu to amd and when i had the intel cpu the Liquid was nearly 15 C colder than the CPU..

Amd cpu's dont report temperatures correctly in windows. Thats why there is a different. The liquid temp would be accurate. As a rule of thumb I always take 60 degrees in amd cpu's as 100 degrees and seems to be accurate then. At least that was the case for my last three amd cpu's

This. Water can't really be hotter than cpu as heat only flows from hot to cold.

I cannot be held responsible for any bad advice given.

I've no idea why the world is afraid of 3D-printed guns when clearly 3D-printed crossbows would be more practical for now.

Eh, some quantum mechanics people and Peltier enthusiasts would disagree, but yeah, water will never be hotter than your CPU unless you just filled the loop after letting the fluid sit out in the sun in a black bowl for several hours.

Alright then, I'll revise my quote. Heat only flows from hot to cold on a macroscopic level without adding energy.

No, this is not normal and it is not how its supposed to be. You're most likely getting a bad reading. Yes, the coolant is there to remove heat from the CPU, however it is physically impossible for the coolant to become hotter than the heat source. Same way it is impossible for your CPU temps to go below ambient on air or water.

That was what i was thinking. I'm not really that mutch into water cooling, but i have advanced chemistry and physics in shcool (around same level as college, just denmark who like to be like no one else..)

LOL, I love how a lot of threads start out like this, with the "Well, yeah. It is what it is, you didn't know that's how it is?" until someone with legitimate knowledge speaks up with "Actually, that's not right because _____ "

 

I also feel that unless you had a second heat source, this should not be so. Something is obviously transmitting erroneous temps...
