Custom Loop Max Temperature Test!

[Mr Mcgoo]

So today i decided to load my cpu and gpu to 100% at the same time for around 1 hour to recorded my max cpu and gpu temp. After a lot of benchmarking i found that port royal (3d mark) demo run used by far the least cpu averaging around 14% load. I was able to load the cpu and gpu to 100% using port royal for gpu and cpu-z stress for cpu at the same time to give me a full insight as to the absolute max temps i would see while gaming.

Temps after 1 hour are as follows:

Ambient 21c
GPU 49c
CPU 65c
Water 29.1c
Fan Speed 1500rpm

While that was running i decided to run prime 95 non avx right after 1 hour had passed to see what temps i would get. It started at 70c before dropping to 66c as waters temp cooled due to no gpu load.

I then decided to run prime 95 avx right after prime 95 non avx and got 84c. i know prime 95 is overkill for cpu's when compared to games but i like to see what my cooling is capable of. During the summer ambient room temp got to 27.5c so i guess cpu, gpu and water temps would have rose my 6c or so.

Overall i'm happy at those temps but i have seen people with lower prime 95 avx and non avx temps on a custom loop with a more power hungry cpu. So maybe my temps aren't as good as they could be?

Your water temps are fine it if its around 30 degrees under load after a heat soak. I suspect issue is the 9600k in your sig, is that its a pretty small chip surface area wise, pumping out a lot of heat and as a double whammy the soldered solution intel used for 9th gen is pretty poor to the point people can delid it and see a 15 degree drop. Add on a heavy stress test like prime and tbh your temps are not way out the norm.

Could check your mounting pressure on the blocks possibly, but don't think your temps look anything massively abnormal, slightly high delta on GPU block possibly over the water temp but nothing I would be concerned about temp wise overall.

my cpu block has spring screws and have no idea how much they should be tightened. all the way or not?

so tightening the cpu and gpu block made no difference so my temps are as good as can be i guess
