High idle CPU temps after cleaning radiator

Today, cleaned out 3 years worth of dust out of my Corsair H100i GTX water cooler, and also switch the fans to pull air into the case so that there is overall positive pressure within my case. As a result of this, my CPU temps have skyrocketed from 35-40 to 80-100c. While cleaning the radiator I did not remove the cooler from the CPU. The thermal paste is unchanged, all conditions should be identical. I don't know what is causing this, I have increased the fan speed and pump speed to maximum to avoid bsod. 

Any suggestions?

is the radiator dry?

As far as I know, no. It was working perfectly yesterday and I have discovered no leaks. When moving the radiator, you can hear water splooshing around.

Does the pump in fact work?

Corsair linked shows a readout of ~3000rpm and one tube is really warm while the other is cool. If the pump was not working, both tubes would likely be warm.

If the fans and pump are both running correctly, perhaps swap them back the way they were before and see if that fixes things. From what you described nothing much should have happened, but obviously something did.

¯\_(ツ)_/¯

Sounds like its improperly mounted (monkey tight...not gorilla tight).  If its hitting those temps right away anyhow.  Or pump failure could be this as well.  Did you forget Thermal Paste? 

EDIT - I just read your post sorry I breezed through it the first time.

 

If its taking 5 minutes or so to hit those temps...are you sure your fans are spinning the right way?

Apply new thermal paste, after 3 year would be good to put some new one on there, and that helps with the problem that it might be that the CPU block is not seated properly anymore could be that you loosened it while cleaning the radiator.

Fans are spinning at max, the pump is at max, CPU hasn't been unmounted since the change. The fans are pushing hella air so airflow is not the issue.

I am definitely going to try that, tomorrow once the shops open.

I assume you moved the radiator to a lower point than the CPU block during the cleaning procedure, this may have moved an air pocket from the radiator into the pump block that needs to be moved around so that the CPU block is submerged in fluid and able to move liquid again. You should shake the system around and if possible shake the cpu/pump block while the radiator is in a higher position.

If you moved the radiator through a different axis it could've caused an air pocket to move. I found with my old 120mm AIO antec cooler that whenever I laid the comptuer flat & then stood it back up quickly, I'd then have to hold it at a weird angle to get rid of what I can only guess is an air pocket in the pipes. Temps would shoot up & it'd whine like a mofo, but laying it flat and slowly raising it up again would fix it. Maybe try this with the case open so you can listen to it, it'll make a rushing bubbly kinda sound as it happens, and sit in the bios watching the temp change.

IMO it is 3 years old and you probably caused air to move causing your issue. Also if you rotated it where pipes are on the top rather than bottom for example then it might not be flowing like it should due to the evaporation over the years taking a toll.

 

I would contact Corsair and see about a RMA as you have about 2 years left of warranty if it is 3 or so years old.

I have same issue as well

After cleaning the dust without removing any thing 

My cpu went up to 100c when it just boot into windows 

It will went down to 50-60c  when idle but if I launch any application the temp will sky rocket again till 90c and will just hover between 70c to 95c 

If I not mistaken my h115i is at least 6 years old 

Could it be I accidentally knock loose thr cpu block that connect to the cpu? 

Or the air pocket was form when I move my case?
