[SOLVED] CPU temps far too high after transporting

[billybob713]

I have never experienced any issues with my current pc, it is about 6 months old and the temperatures have always been fine. However, I traveled home yesterday and decided to bring my pc home which meant checking it and bringing it on a plane. I stuffed the internals with newspaper and packaged it with a metric ton of bubblewrap. When I got home, the pc booted fine and gave me no issues, but I noticed I was getting low fps and I checked the temps through NZXT Cam and the CPU was wildly overheating. While idling, the CPU was regularly hitting temps around 80 degrees Celsius and while playing games it was hitting 100 degrees. However, I can't tell what the issue is. All the fans are running fine and the heatsink seems to still be in place and tightened down. From what I've read online this seems like possibly the connection between the heatsink and the cpu was disrupted and I should reapply the thermal paste, though I would like to know what other people think?

The GPU is running at low temps and the actual computer doesn't feel hot at all. I have a AMD Ryzen 7 3700X 8-Core 3.6GHz, and a NZXT Kraken M22 CPU cooler. Any help would be greatly appreciated!

What pump RPM is Cam reporting? Sometimes a tiny amount of air can be trapped in the pump after the PC has been moved about. I had it happen to me with a Kraken x62, and all I did was move the radiator from the front of the case to the top. So it doesn't neccesarily take a lot for it to happen.

First of all, I noticed that the CPU temp was extremely high, but also that the pump RPM were way above spec, around 3300 rpm compared to a normal maximum of 2700 rpm.

There were no unusual sounds or other indications of problems, just the high temp and high pump rpm

I disconnected my PC and gently moved my PC from side to side, and in all directions, almost turning it upside down.
This let the air escape from the pump housing, and cooling performance, pump RPM and temperatures returned to normal.

Replacing the thermal paste also seems like a very good idea.

I don't think CAM is reporting any rpm for the pump. This is what CAM is showing me.

Meant to post the above as a reply

Is that the most recent version of Cam? The Cam software I used until recently looked quite different, and it reported both pump and radiator fans RPM.

Which header on the motherboard did you connect the pump tachometer connector to? If connected to CPU fan header, for example, you can tell the RPM by using software such as HWInfo (or look in BIOS in the monitoring section)

Is the cooler connected by USB to the motherboard on an internal USB header?

EDIT

But even without knowing the pump RPM, you could try to move your case about as I suggested, to see if that helps, in case it is air.
If that doesn't work, at least it crossed one possible problem off the list

If it doesn't work, pump RPM would be very usefull: If it is spinning to slowly, the cooling performance will be severely impacted

Ah I was able to find the pump rpm using HWInfo.

So I guess it is running at 3800 rpm which I would assume is fairly high. Would this imply that there is possibly air stuck inside the pump? And the solution would be to rotate the pc aimlessly and hope it escapes or is there a method to the madness?

The pump also does not feel hot although I don't know if that means anything

After the similar experience I had with my Kraken x62, and considering your pump is running very very much above spec, I think it is safe to assume you have air trapped in the pump.

But you wont know until you have tried the solution I suggested. Take your time and cover all angles. You could consider uninstalling the cooler to do it, but it should not be neccessary

But a pump running at close to 4000 rpm is extremely fast and not anywhere near factory spec. Eventhough I had an x62, and yours is an M22, the pump shouldn't spin that much faster

EDIT: For comparison, the pump on the x62 is maxed out at 2700 rpm, but when the PC is not being stressed, it goes all the way down to 2000 rpm

Sorry, I forgot this part in my previous reply.

The idea is to let the air escape from the pump assembly. As you know, air wants to rise to the top in water.

So taking into consideration where your radiator is mounted, you want to let the air escape towards the radiator. But cover all angles, it is not a straight route through the system. For example, look at the bends in the tubing, to make sure the air is not trapped there now instead.

It took me less than a minute or so, so it is an easy fix

So I've tried rotating the system pretty much every way possible but it doesn't seem to have made any difference, the temps are still very high and the pump rpm is still around 3900 rpm. Could the pump rpm be high just because the cpu temps are too high and it is trying to compensate?

EDIT: Was just on the phone with NZXT and they said the impeller inside the cooler was likely broken and that's why the temps are so bad. So the only option is to get a new cooler, figures. Thank you for the help though, it is greatly appreciated!

I would have guessed that the pump rpm are unusually high due to reduced resistance or mass from the water, but I have no real technical knowledge when it comes to the internals of an AiO, so I'm probably wrong.

In my case, the rpm were high when there was air in the pump, and the rpm dropped significantly and stabilized at normal speed once the air was gone.

To be honest, close to 4000 rpm sounds a little excessive, even if it is trying to compensate for higher than normal CPU temp, but not impossible.
But if it is trying to compensate for the high CPU temperature, it would indicate that the AiO's performance is reduced somwhere else, and that would lead to the radiator fan, and you say that it is working as ususal.

But I'm partly speculating, so don't take my opinion as fact, I'm not experienced in that area, and I haven't looked up the actual specifications of of the pump in your particular AiO, which I admittedly should have done

EDIT : I looked up the specs of the pump on your AiO. Max RPM are listed as 3000 +/- 300 rpm.

So in your case, it operates 600 rpm above maximum estimated rpm (3300 rpm), which is not as much as I initially thought, but in my opinion it is still too far outside spec to be completely ignored
