Overheating CPU problems

Hi guys, I need some help. I am having an ongoing problem with my CPU overheating. I have limited hardware knowledge, so between that, common sense, and Google, I can't figure this out.

My CPU started overheating about a month ago. I cleaned out the case with compressed air, confirmed all fans were running, removed the heatsink, cleaned off the old thermal paste and reapplied (that worked for 1 day before it started up again), and have even left the case open with a fan blowing directly into it. That kept the temp down enough that it wouldn't shut off (60-70C). After a couple days, it magically stopped overheating and was fine for a couple weeks. Until today, temps shooting up to 105C and overheating. I've got the fan blowing into the case again and it's maintaining at about 70C and sometimes shooting up to 90C.

The computer was a custom build from CyberpowerPC and is about 2.5 years old. Here are the specs from the order sheet. Everything is the same except for the RAM, I upgraded that around the beginning of the year. (No overheating problems anytime close to the upgrade).

I thought maybe the liquid cooling system needed to be maintained, but from my research the XtremeGear 120mm is a closed system and doesn't need maintenance.

How are you applying the thermal paste? Also are you making sure the cooler bracket is tightened properly, so it is making full contact with the CPU?

Also a good idea to check the heatsink/radiator for dust.

I used whatever they sent me with the computer, probably a generic or somesuch and not top of the line.

I downloaded Core Temp found here: http://www.alcpu.com/CoreTemp/ I downloaded a seperate GPU temp monitor to check that but the video card seems to be running at good temps.

I made sure to look up how to apply the paste correctly. I cleaned off all the old paste with alcohol, let it dry, then applied a small pea size amount in the center and pressed the heatsink back onto it evenly. Everything was tightened down correctly. The heatsink is all enclosed, with no fan visible. I did extensively blow out the entire case, repeatedly.
 
yours seems to be a quite cpu cooler...first of try cleaning the heat-sink of dust and then use a fan to blow air through it.

see the result.

you can also check if your mounting is correct or not be using the pc for a little while and then touch the heat-sink with your hand and see if it is becoming hot or not.
 
The odd thing about this is the irregularity in which you are having the overheating, if the thermal compound was substandard or unevenly applied then you would be having issues all the time it sounds more like something may be going defective and the first part I would guess it the heat sink. It could be the enclosed pump that is failing or even slowing own.

Ya might be putting too much thermal paste on it. I had an ALIENWARE custom build & it did came with a 5yr warranty. You should at the least just have to pay shipping & let CyberPower fix it. They should've benchmarked it & also did a burnin on that system. You PAID FOR THAT---THINK ABOUT IT 2.5YRS. You shouldn't have to worry about system overheating.
