Can you confirm if these temperatures are suitable for a custom loop?
Can you confirm if these temperatures are suitable for a custom loop?
Hi,
this is my initial post here, and I'm actually seeking assistance regarding liquid cooling. I believed I was managing it well, but I realize now that might not be enough, especially since my latest build is already hitting temperatures in the 80s under load before I even begin experimenting with overclocking.
My current configuration:
* [Case] BeQuiet Dark Base Pro 900
*
[MB] MSI Z370 Gaming Carbon Pro AC
*
[GPU] EVGA GeForce 980ti Hybrid
(waterblocks removed, replaced with full EKWB cover block)
* [CPU] i7 8700k with EKWB Supremacy EVO waterblock
* [PSU] EVGA Supernova 1000 P2
*
G.Skill Trident Z RGB 32G (2x16) 3200
*
Samsung 860 EVO M.2
* Kingston SSD 500G
The loop relies on a 420mm radiator at the top of the case with intake fans, plus a 280mm front radiator with intake fans as well.
Exhaust is managed by a single 140mm fan at the back of the case.
Previously, I used a 2600k CPU on an older motherboard, and my temperatures stayed below 50-55°C. Now I've reduced the tubing considerably, expecting further cooling due to longer water circulation in the radiators, but after the adjustment, I'm observing temperatures reaching up to 80-85°C under moderate load.
I performed a 15-minute stress test in Prime95, which recorded an 83°C on the CPU sensor and 94°C on the MB sensor... (this was using the latest Prime95 version with heavy CPU usage; all cores ran at 4.2GHz).
Below is the assembled loop image.
I'm not sure what I might have done incorrectly to cause such high temperatures...
The only change I’m certain about is that the front radiator fans (2) are connected to the MB pins, whereas the top radiators (3) are linked to the GPU PWM pins and controlled by the standard case fan PWM splitter.
Compared to my previous setup, all fans were previously managed via GPU PWM through a non-standard split. However, since they're spinning and the stats show they're reaching maximum RPMs, I don't think that's the issue.
🙁
Help?
PS:
I've already checked everything thoroughly.
I can't find any signs of air bubbles in the reservoir (the liquid level remains stable, no bubbles present).
I briefly disconnected the pump PWM cable to test at full speed, but it didn't help.
I set all fans to 100% PWM and still saw no improvement.
Intel's performance is overheating, requiring thermal paste between the die and IHS for better heat dissipation. The 80's generation is adequate, but at 4.2Ghz it's too high. Consider reapplying thermal paste to the CPU.
Intel's performance is strong, but the thermal paste between the die and IHS makes it difficult to remove heat effectively. The 80's generation is acceptable, but at 4.2Ghz it's still too high. Consider changing the thermal paste on the CPU.
