Higher CPU temperatures than usual

[PedroL2000]

My CPU is currently cooled by a Lian Li Galahado AIO and I've always had both my case and radiator fans pretty silent. However, coincidence or not, I was playing normally then had a short power outage, which instantly turned my PC off, but when I turned it back on, I realized the fans were louder, so I checked my CPU temps and it was hitting 65 Celsius degrees. I thought at first I could be fixed by simply restarting (don't ask me, but sometimes when I turn my PC on my AIO pump isn't working and I have to go to BIOS and change the flow rate manually). Sadly my fans were still loud even after I checked my AIO flow rate and temps were still higher than usual. I didn't check my temps for ages (I used to get between 40 and 50 Celsius degrees), so maybe it gradually increased and I only noticed it now. I can't diagnose the problem, so I do want to ask about a few possibilites:

1. Could the power outage (it was a casual power outage, not a lighting) somehow have damaged the AIO?

2. Could the AIO readings be wrong, since its flow rate is said to be 40L/min (max) but the CPU isn't cooling?

3. Could it simply by a thermal paste issue? I'm out of thermal paste atm but already ordered

4. Althought I think it's unlikely, could this be a software issue?

AIO readings are fine, air flow in case looks fine, there are no broken fans, the filters are cleaned. My last hope is the thermal paste.

Are you using any software to control the speed of the fans? I highly doubt the power outage did any damage, since a power outage - AFAIK - is the same as simply powering off the computer normally, through the PSU switch, or using the power button while in the BIOS. The only difference is now you're running software that is more vulnerable to corruption when the machine is suddenly powered off.

The only software I have installed is MSI Afterburner

power outage can and in a power spike when power is turned on again... that can kill components. 

if you install hwinfo64.. or in the lian-li software does it show that your AIO has any RPM on the pump? 

 

 

or if you connected it to your pump fan port does it show any life? 

40L... is low.. my flow meter with a D5 pump shows 240L.. if it goes below 65L it starts beeping.

Did you have any profiles configured within the BIOS at all? What speed does the AIO report for the pump?

Thank you for all the responses, but I think the AIO is the issue. I did reapply thermal paste and nothing changed. However during my research I've encountered with an official note from Lian Li saying that several Galahads made before March 2023 (which is my case) were returned with several issues, mainly clogging, so I assumed it's my case. I've already bought a Scythe Fuma 3 to see if it helps and use temporarily during the mean time when I RMA my AIO.

Did you check the pump speed and the settings within the BIOS? Seems too late at this point though.

Yeah I did, it's full speed. And even when I'm in bios, CPU hits 50 Celsius. That's too high for water cooling isn't it?

Yup. 

If the flow rate is accurate and your temperatures are like that in BIOS, you probably have a build-up issue within the block/pump area.
