i7-4770k temp creep with AIO - solved, poorly cooler

[Cyber-Mav]

Another day another water cooling disaster. Its not a matter of if its gonna fail but when. H100 has track record of being unreliable. Whens last time someone posted on here saying their block of aluminium air cooler fell apart?
Water cooling was always a fad when it first came out and everyone was recommending it. Once some years went past and the pump failures and blockages started cropping up people jump back to air coolers having learnt their lesson.
You got 8 years out of and now have to spend more to replace it. Had it been an air cooler at most all you would need to do is replace the fan.

Update: whilst it was at 38-43C in BIOS, by the time I'd booted up Windows and downloaded some temp monitoring software, it was at 100C! This is not overclocked.

I'm glad I preemptively ordered an air cooler!

I'm surprised it didn't cut off. Shouldn't it do so?

They just clock down to stay at 100c or less

This is a very good point. Unless you get someone using liquid metal TIM on their ali block!

I went with AIO back then as it was my first self-'made' PC and thought it would be the quietest option, short of doing my own loop. Seems like actually Noctua's air coolers may be more effective and quieter, depending on the fan locations of the AIO.

Looking forward to seeing how the air cooler performs. I may still need to do the suggested delid anyway, if this cooler also doesn't keep things low enough.

Ah interesting, that would explain why it was going 100 then high 90s then 100 again.

I did set a warning in the BIOS for an alert if reaching over 80 but that doesn't appear to have had an effect.

If you have access to a bench vice/vise it's a simple enough process to delid the CPU in preparation for the arrival of your new cooler.

It arrives today, so I'd like to try without delidding first, just to see if it's really necessary. I now understand it's a really quite simple process, but it's still a process that can go wrong! I'd rather avoid that step for the time being whilst I steadily test all the components again (this all started with random shutdowns that I think were caused by the mobo, but I'm checking all parts during the reinstall). I'll then delid once I can be sure all other parts are working as they should.

I think after 8 years, it'll have lost a decent amount of fluid. My old H100 was still in use in a friend's system until a year ago. He swapped to a cheapo Arctic tower cooler and the difference was significant. AIOs are good, until they aren't.
Not sure why that wouldn't have shut down. I thought Haswell's max was 100.

I'd far rather have a decent Noctua tower cooler, like you've ordered. You'll probably find it's a lot quieter with it.

AIOs do have quite a drone hum from the pump block versus real pumps. That is one of the things I don't like about AIOs. They're not terribly loud but you can hone in on the noisy area.

It is very quiet indeed, and so very cooling too. When I first turned it on I thought it was DOA because it was so quiet that I could only hear the PSU!

I also really, really like the way Noctua have done their instructions. They took a minute to completely get, but it's clear they're very particular about getting things right, and want you to be super careful too; much better than some other companies with quite loose instructions that can be rather open to interpretation.

It also came with a tube of their TIM, which I was not expecting! An added bonus.

However, the pump is now clicking quite a bit, presumably air bubbles. Hopefully they'll dissipate with time.

Best thing to do is power it up, and tilty wilty the pc to free all the air from the pump so that it flows to the highest point in the loop which should be the rad.

Thank you for the suggestion - unfortunately I already tried this repeatedly as I'd removed everything from the case, but to no avail. It did stop the clicking when I tapped on the rad, but returned after a few seconds.

I think it may be quite poorly given the lack of cooling it's been doing!

Tis a sad day.

If you are looking for recommendations, I am currently using the Arctic Liquid Freezer II with my i7-4790k for the past good few years without any problems.

I have also used the Antec Kühler H2O 920, and continue to in my backup pc since 2012, without any problems at all.

Thank you for the recommendations - I've in fact already installed a Noctua NH-U12A which arrived yesterday, and it's performing admirably thus far. This episode with the AIO was the final push to go to air cooling - do not get me wrong, this Corsair one has done very well the past 8 years, it's been doing exactly what it was supposed to. I just always had a niggling concern that it would leak onto my GPU, so whenever I heard a trickling sound from it, I immediately got into the PC case to check! Of course, it never did do so, but I think I like the peace of mind of there being no possibility of an internal component leaking onto something else now.
