Bit too high temps for custom loop?

Hello, yestereday I build my first water cooling custom loop but after few benchmarks I think these temps are too high.

Loop: Monoblock X370, RES100 Revo D5, SE240, 16/10 tube, Pump is regulated by motherboard and runs between 1300 to 2500 rpm, but even with full power temps are basically the same.

Running:

R5 1600X @ 3.9GHz with 1.4V and in idle cpu is around 30-35C, VRMs at 40-41C. At load cpu hits around 63C and vrm 72.

With aircooled setup temps were in load at cpu around 70-73C and vrm around 80C. CM Hyper 412S with 2x Enermax Magma 12cm at 1000rpm.

 

Well the case is CM 690 first gen and fitment was interesting but I always wanted to put custom loop in this case - I have it since it came out. I knew modifying few holes would be needed.

GPU is getting little bit hotter but when 1 fan is practically blocked its understandable. Also part of radiator is blocked by sheet of metal on top but I dont think thats the problem, Block seems to be seated properly.

Filling went easily and bubbles disappered quickly, its small loop.

Hi . I've never had amd cpu before . However I experienced the same problem on a i9900k with a kraken x72 cooler . The issue was that turbo boost was enabled in my bios . Turning this off helped quite a bit as it seems turbo boost at the moment is a bit unstable

The water obviously gets warm, so the block is fine. I'd guess either the rad's fans are running too slow, or they aren't getting enough air. I'd definitely try messing with the rear exhaust fan. Slowing it down, stopping it, removing it, turning it around.

The gpu's temp increase is most likely due to the res blocking its fan.

And I'd suggest finding the highest inaudible operating speed for the pump, and setting that as the lowest speed in its curve. Then at 50 or 60 C its speed could be increased further. Just don't run it unnecessarily slowly. (the same goes for fans btw)

Thanks man, I turned around rear exhaust fan, so now it is intake and it helps. Temps droped on CPU about 6C and on VRM by 9C. Fans on rad are spinning at 1000rpm and I can clearly feel on outside top of case the airflow.

Now I will try to mess with pump rpms.

Yeah, same, to reach 4GHz I have to push 1.5V.

But now I have at load (aida64) 56C and vrm 63-64C so, thats better.

Still, I’m very tempted to buy fractal R6, another 360 rad and add gpu to the loop ?.

I really enjoyed putting together this loop.

Could be a lack of air. 

Do you have decent air coming it and better fans to try on the rad?

Well your temps are like that for many reasons.

 

-Lack of air / bad air ventilation. You case has to has good airflow with enough fans to work like intended.

-Your volts are so high. You are running on 1.5V which is pretty damm high.

-The rpm on fans and pump are too low

-The fans are done wrong.

-Something is blocking something

Wanted to call attention to this picture. You are choking the radiator by using the wrong holes. You should be using the second set from the bottom. On my phone, but I will try to update this post with proper mount location.

The amount of fresh air coming in, is garbage.  The air flow is terrible on this case, and with the gpu being enclosed,and  heating up, all that extra hot air trys to escape from the top.  It makes sense that under load it gets hotter than normal.  You need a case that has good air flow and you wont have these issues....

I had to mount it like this, because in original holes it would collide with motherboard.

Yeah, airflow is really bad, when I turned rear exhaust into intake it helped, but still there is not enough of airflow.

You are right, only I´m running 1.4V which is a bit high but 1.5 would be too much.

 

So, I´m gone start looking for new case, but I have on my mind Fractal R6 or Corsair obsidian 750D. I need 4 ideally 5 3.5" bays, fit this 240rad and another 360 rad. I don´t need glass panels, rgb, stuff like that. Any suggestions?

It is a soft tube build, to see the best temp possible - remove the rad outside the case so it has no restrictions and run the same stress test, it is highly possible that your case is just too old and it is the bottleneck

After couple of months and few upgrades, waiting on parts I have fully custom loop. I added for gpu block Watercool heatkiller IV with backplate, alphacool nexxos st30 x-flow and changed all fans with noctua f12. And put it all in Fractal R6. Temps are quite good - in games cpu around 50C and 45C with liquid temperature around 38C. I didnt test it too much for now, also cpu and gpu are stock. Pump is at 45% and fans are running at 650rpm. Im gonna play with OC and pump and fans speed in proces. I want to test different setups for longer time.
