[SOLVED] High temperature after cpu froze

[Wdemo]

Hi, i'm asking for help if it's possible, my cpu is reaching almost 100° in temperature after a problem happened. I left my computer rendering some work for about two hours and when I came back, it was like turned off , for the number of the images that were rendered I can calculate that it worked for almost 30 min after i left, and then it crash, i turned it on again but it was reaching that temperature rapidly. I'll write some facts to help understand the problem:
My cpu is a i7-6800k and i have never used in overclocking mode.
My Cooler Is a Corsair h60 and it Is heating high too, including tubes.
I usually work with programs for 3D which requieres a good system , but I do not work forcing the pc.
I cleaned up the pc about 3 months ago, and until now it was working fine. (It Is not dirty either)
I bought all elements about 5 years ago.
In BIOS mode temperature also increase rapidly to 90° starting from around 34°, here the cooler Is heating high too and fans are working at máximum but seems not having effect.
My motherboard Is an Asus x99 AII.
My pc starts and works as usual but getting slower, I notice the problem because fans were at máximum after Turning on the first time.
After a fews restarts my pc take More Time to start until it gives me the message of critical temperature. I tried again once it was cool but it hace the same result(high temperature)

I think that maybe my pc tried to got suspended and maybe it tried to work with fans off while being turned off? (could be it?).

Thanks in advanced , until now I'm hoping that I just have to replace the cooling system but Im not sure that this could be the problem(also, how can I know if it Is working properly?, Could the pump or the liquid be damaged in some point? ) , some of you have faced some similar problem?

Really sorry for my english, but I think Is understandable, any sugerence will be welcomed, thanks!!

it's possible that the thermal paste was affected when the temps got very high for an extended amount of time.
i would try re-pasting and see if the temperatures improve any.

you can also create more aggressive fan curves, and add fans if possible, throughout the system to get more cool air in and more heated air out.

also, maybe look into a larger radiator.

5years for aio cooler is too long, pump seems to be dead at this point, replace your cooling

 

[mdd1963]

If one tube is noticeably heating up, I'd say the pump is simply no longer pumping, or, simply failed...(a common condition for AIO pumps after 18-36 months use, where contaminants/hard water deposits, etc. often clog pump internal microfins making the heat dissipation next to nil...

Thanks!!, yep, I changued the thermal paste (kryonaut) but the problem remains the same, and fans are at máximum

Thanks!! I really hope this to be the problem, its the cheaper one. I will wait for some other opinions just in case.

most AIOs usually have up to a 3 year warranty but you should check yours.
though 5 years is really cutting it.
there's a chance Corsair would honor an RMA.

Oh it could be, Is it possible to replace the liquid or it needs to be conmpletely changed?

 

[JohnBonhamsGhost]

Is it possible to replace the liquid

if the pump is dead it still couldn't push any newly added water.

The H60 will generally last about 5 years, as will most all nzxt, Corsair and other vendor units that have history.

The failure point at that age isn't generally the pump, but the coolant. With time and heat the coolant starts breaking down into its individual molecular components, one of which is oxygen. Oxygen is a tiny molecule in comparison to many and unfortunately, even as non-permeable as they can make the rubber tuning, oxygen is small enough to work its way through the gaps.

Without the oxygen to help keep the fluid in a viscous state, it thickens up and the coolant level drops to the point where the pump is starved for new fluid, and it just recycles the same fluid in the exhaust pipe, heating it up drastically, which exasperates the chemical breakdown.

Temps go through the roof.

As is, even with torture testing, such as long renders and max cpu usage, a stock 6700k only pulls a little over 100w, so the 140w H60 is plenty big enough to handle that load. The hyper212 evo is equitable, but the Arctic esports duo would e a better choice all around. Bigger won't necessarily be better, the temps will average out pretty closely, but a 240mm AIO or a H80 class thicker rad aio will have a capacity advantage, which will lower fan speeds at max cpu a lot.

Thank you so much, since all replies point to the cooler as the main problem , I'll be changuing it, I also was suspecting about it but I wasn't sure, your replies here make me feel relieve c:

thanks to all!!, I replaced the cooler and everything works fine!!

PD: I'm not sure how to close this thread

You don't actually, you've marked it solved, the mods will end up closing it to replies after a while, to prevent pointless necro posts.
