Hello Forum Community,

The other day I noticed on my wife's PC while we were playing a game her processor (i5 3330) via coretemp was running at almost 220 degrees F. Obviously concerning. When I opened Speed Fan it read that only one core was running considerably hotter by about 50 or more degrees than the others.

The whole computer got laggy so I shutdown the game let the computer idle for a few moments while I removed the side of the case to check if maybe her cooler( I believe is an H100 single fan water cooler, been awhile since I put it in to remember) had popped a mounting pin or something.

It hadn't, but the outflow water tube felt very hot, so I shut it down to let the whole system cool off and made sure that the radiator was clear of dust and rechecked a few hours later. Still has a hot core via Speed fan. Coretemp reads 150F idle temps. I also installed CPUID HWMonitor and it shows 90 C idles temps. So I told her to keep an eye on it and maybe its a bad sensor or something. Then last night she had a blue screen and the computer is taking a long time to boot up.

Her Specs;
i5 3330 at 3.0 no OC
6GB RAM
Gigabyte Z77-D3H
H100 cooler (I think, cant remember)



Trying to upload a pic of HWMonitor just above this, but it doesn't show up in the preview so it may not work...

Could the processor be in the process of giving up on life or could it be something else? Thoughts or opinions?

Going to try replacing the thermal paste when I get home from work but looking for thoughts/advice.

Considering AIOs I'd say maybe pump failed. Usually with these models, the most common issue is pump failure. If you have an alternative cpu cooler (from another computer), that you can canibalize for a period of time, try mounting it instead, just to check it's not something with the mobo.
Are your fans on the radiator spinning?

Unfortunately I don't have another cooler to test. But I have a small PC store in town I can pick something cheap up on my way home from work. Didn't even think about the pump itself. And I had my wife look at it for me to see what it was, it's an Antec H20 620, off my older build so it's about 5 years old or so.

Yeah most aios have warranty of 2-3 years because of the pump as it's a very common fail. Still, I suppose it could be the fan on the radiator, double check if it's spinning.
If you want a cheap but good air cooler that you're likely to find locally, look for hyper 212 EVO. Shouldn't be more than $30 and plenty sufficient for that cpu.

So I replaced the AIO with a hyper 212 evo and it's now idling at about 35C....much better. Seems that the pump did fail.

Thanks for the help!

Now I just have to worry if there is any lingering damage to the processor from the heat......
