Cpu cooling completely Inefficient

13 hours ago, TechNovice0010 said:

I ve checked rest of possibilities and appears that AIO has air bubbles stuck in radiator, sound is noticeable when it reaches max rpm.

Pump is running, it is properly connected and it isn't loose. I've checked voltage and is 1.072, which isn't high,I've turned off asus oc just to double check and nothing changes in regards to thermals. 

time to swap it out then.

 

before mentioned NH-D15 is a nice choice, but in hindsight the be quiet dark rock pro 4 is a more "visually appealing" choice too, for example.

My pc is closing in on 2 year mark at march of these year and I was running some tests in CinebenchR20, 3DMark etc. All pc components work as expected, even above expected performance except cpu(i7-8700k). Cpu is extremely underperforming with R20 score of 2993,that got me suspicious to my cooling(AIO CoolerMaster MasterLiquid 240 lite), so I run HWmonitor for temperatures. Temperatures were sky high, idle temperatures were 45-50°C, temperatures when working on some low load programs is 50-65°C and temperatures when working on heavy load programs or playing games was 85-95 °C EVEN reaching 100°C on all cores when 100% usage, although pc doesn't crash and works fine I am still scared, these temps. are to high even for 8700k.

I was suspecting on thermal throttling 

So I was thinking of replacing this aio

with Nh-d15 or some other better aio. Cpu is factory overclocked to 4.3 (Asus mobo) on all cores but that throotles down to 3.7 on all cores when I run heavy programs for aforementioned reasons. I need advice fast. Thank you and sorry for bad grammar.

I would suggest to get a top end air cooler, you will be way better with it.

Ambien temperature is close to or lower than room temperature most of the time,(20-25°C i would say), case has vary good airflow (cooler master Mastercase Pro 5).

before following above posts pushing you to spend money.. few things to try:

- verify your mount is still solid. i've fixed my neighbor's performance issues not too long ago by just pushing the pegs of his stock intel cooler back down properly (they had come undone for undetermined reasons..)

- are your aio fans running?

- verify the pump of your aio is running (you'll feel it vibrate, or hear it "purr", unplug all other moving components to make sure it's the only noise.

- if the pump isnt running, it can just be the header, the 3-4pin fan connecters arent the most wear-resistant. maybe just wiggling it makes stuff magically works

- did your cooler lose a significant amount of liquid? (you'll hear it "bubble" if it has a large amount of air inside)

- what are the OC settings? maybe it's just setting the voltage stupidly high.

 

probably, by the time you've went trough all that, you'll either have fixed your issue, or found what exact issue needs replacing.

 

that said, something to worry about with the NH-D15 is that if you have a motherboard where the GPU is in slot 1, it'll most likely interfere.

AIO fans are definitively running as they are loud when temps reach ~75°C.As for other things I'll have to double check. Though  I can hear some weird noise from time to time when it reaches 70°C,i think that It could be air bubblee, I'll try to isolate sound and record it. I'll come back after few hours with results.

recording doesnt help much, but if your pump makes weird noises that's a reliability concern as a whole.

Pump is running, it is properly connected and it isn't loose. I've checked voltage and is 1.072, which isn't high,I've turned off asus oc just to double check and nothing changes in regards to thermals.

Noctua D15 is an awesome air cooler, but make sure you have enough clearance for the RAM and the case lid as it is tall. But if you can get is in there, you will never have to worry about temp issues, if installed properly.

Yeah, I tried to get rid of bublee but unsuccessful, it is way too much of a problem for aio to stay in the system as temps could damage cpu. Thanks for suggestion on dark rock pro I'll look into it.
