Cooling a 5800x

I currently have a cryorig A80, and it is just pegged at 90C all the time in games, idles at around 55C, spikes up to 80s just on the desktop for long periods (basically if it isn't completely idle).

So either my A80 has finally kicked the bucket (I do get warm air from the side the hoses enter, but not hot and the far side is usually cool) or it just isn't up to it. Repasting did nothing at all. This is with a mild undervolt btw.

So while I'm not majorly concerned about these temps, the noise is a lot because the fans are just at full tilt all the time and the A80 doesn't seem to allow for separate pump and fan control (there's a harness off the pump that splits to take both fans). Even so, at 100% fans and pump it still can't hack it.

So I'm considering a 360 rad AIO. Am I on the wrong track?

Have you tried enabling LLC with a more aggressive voltage negative offset?

What is your current voltage drop? I applied a negative 0.2 offset and my temps when down quite nicely with my 5700X with LLC mode 3 enabled (mode 1 = quite mild, mode 5 = high, 3 is moderate).

I tried a negative 0.3 offset but the system isn't stable with that.

It's been a while so can't remember my settings, but I do have a negative offset applied on voltage (and a +100mhz offset too which is stable).

Not at my desktop now, but it was the lowest I could get it while stable.

Ok so yeah, sounds like your current cooler is probably overwhelmed with either the pump at minimum or contact not being 100%.

I reckon that pulling it out and reapplying thermal paste and checking mounting pressure would be great.

You could easily just get a known good AIO like the Arctic Freezer 280mm.

I actually moved my pc into a new case about a month ago, gave the whole AIO the best clean it's ever had (along with every other component), fresh paste etc, and temps on the CPU didn't move an inch. So I am fairly certain the rad is not the bottleneck but the pump must be gunked up

I'd hate to see the Corsair H80 120mm of mine that's been in use from 2010. Strangely, the flow rate or assuming the speed of its propeller hasn't decreased. It still spins at 1400rpm and no temperature issues. It's had a lot of use though.

I remember all the rage for these AIO of Corsairs back in 2010 and people using them with Sandybridge. I believe the popular model back then was the H50?

Those chasing the performance of push/pull, pull or push as well as them cutting out fan shrouds as a spacer for no dead spots. Some doing it that way for push/pull with two fan shrouds cut.

Crazy seeing it back then. They changed the block in 2011.
 
So I have my arctic 2 360 AIO on, and I am now boosting to 4.4ghz box stock and hitting 79C in prime95 (with fans whisper quiet), which is much more reasonable and leaves me some room to twiddle with undervolting etc.

Thanks all, seems my old A80 had just had it.

Glad it is all sorted in the end.

6 year guarantee with Arctic so good for at least that long. Just as a matter of interest did your box have a sticker on it to say it has had the gromit replaced?
