My CPU is running at 80C on idle, NEED HELP

My CPU used to run 30-40C on idle (which is kinda hot, but I live in a generally hotish/warm place). I am cooling it with a Corsair H110 AIO water cooler. I bought and installed both about 2 years ago, and haven't had any problems until now.

Last week I decided I wanted to upgrade my GPUs cooler, so I moved my H110 over in the case to make room for when the new GPU cooler arrived. At first things seemed to keep working but this week I noticed that games I started were stuttering on and off. I thought it might be my GPU but my temperatures were fine, and I couldn't imagine anything had magically changed with it (since I hadn't done anything to it). That when I noticed my CPU temperature was 95C. I shut down the game (which was running for about 30 seconds to a minute), and waited to see if the temperatures went down... which they did... stopping at 80C.

I shut down my PC, waited for it to cool (a couple hours), and restarted it. The first thing I did was open MSI Afterburner (which is running on start up *hidden*) and saw that my start up idle temperature was 77-80C.

I've since removed, cleaned, and repasted my CPU cooler. There has been no change. I've see that the fans on the cooler are running (push configuration *just like when the temps were 30-40C*), and I think I feel the vibration of water flow in the tubes while it runs.

I've considered that MSI might be giving me incorrect readings, but my CPU is clearly running incredibly slowly now. It takes several seconds to open and close Mozilla Firefox (without doing anything beyond opening and closing it).

I hope someone here might have a suggestion that can spare me from buying a new CPU. The thing was costly (I my opinion worth it) but I can't afford to replace it right now :(.

Thanks in advance.

Do you by chance have any kind of an air cooler you could try on the CPU? I had an issue about 2 weeks ago where i swapped out my CPU for a 7700k, placed my H80i v2 back on and every game was framey as all hell. CPU temps sound like they were identical to yours. I installed an old intel Stock cooler and everything started working just fine. Paid $35 for a Cryorig H7 and have not looked back[/quotemsg]

I don't have any other CPU cooler... the H110i is the first one I've bought for this PC, and I bought the intel card by itself. I'm willing to consider trying a new cooler, but if my chip is the problem (not sure why it suddenly would be after it was working fine before), then that's money I could be spending on a new chip... It really is...

whoops wrong button for the answer vote, sorry about that. I'd advise trying an air cooler and seeing if you get improvements. I can't imagine a chip becoming the problem, its quite a stretch. With a cryorig H7 being roughly $35 retail id say give an air cooler a shot. if you have amazon prime then the worst case scenario you return the cooler. I actually get better temps with it than i ever did with my H80i even on my old CPU. I idle below 30 and never exceed 76C under 100% load

It definitely seems like something to try. My brother has a CPU cooler similar to that one. I'll get it and see if there's a change. Thanks :) FYI, I'm not picking your answer as the solution until I actually know it is (but fingers crossed :p)

I'll update here when I've done it and got results.

Turns out that my pump had died on my Corsair H110... maybe something I did when I moved it. I swapped it out for my brother's CPU cooler and it worked fine. I've since bought a replacement watercooler from Thermaltake with is doing well... max temperature's 56C while gaming so far. Thanks for the help :)
