Water cooled pc wasn't overheating after crash it does

Specs: Windows, I7-7700k
Hi, I was on my pc the other day and for the last year or so just fine temps for pc always below 34c and gpu under 30c oc to 5.2hz stable. A few days ago my pc crashed and when I rebooted my temps now read over 74-86c when doing task. I can't ever clock it Las 4.7hz with out it overheating. I reset everything on the pc to start from scratch but it still overheats I've made sure the loop is clear and coolant is good also check both pumps and both are working fine.
I sit at 34,36c when I'm not doing anything but other then that it overheats. I'm not sure if it's my settings or what but if anyone can help that would be great


I7-7700k
Prime z270-a mb

Gtx 1080ti strix of

2×1tb hd
2x radiators for each pump
2x 1000ml thermaltake resovors
13 fans
Gpu cpu and ram all have water blocks and
Cpu and ram share the same loop
Gpu has never overheated even after crash
This set up was time for years untill after crash

It is possible that the CPU water block shifted or become loose. Try removing it, cleaning the thermal compound off, reapplying a fresh application and securing it again.

I know that you get less air circulating around in the case with a water system but 13 fans??? I cannot conceive of that number in one system. Maybe 2 per radiator also working as exhaust fans and 3 front intake fans. That' 7 fans unless you are counting the power supply fan then it is 8. Side fans are useless and should be avoided. Where would you put 5 or 6 more? If the radiators are external from the case then maybe two more for exhaust at most (back and top).
Though my i5-8690K is not OC as high (4.6GHz), I keep mine quite cool with one on the air cooled CPU heat sink (Noctua), One front intake, one exhaust at the top of the rear and another at the rear of the top. That's 4 really. If you add the one factory installed on my GTX950Ti, that's 5 and one that is part of the power supply so all in at 6 if you count all. 25-28C idle, 30's to low 40's C under use and never much over 50C max. I could easily go 4.7 or 4.8 GHz without adding the second fan to the heat sink and keep the temps reasonable. Sorry, but I personally do not see the need to go to a liquid cooling system which are complex and more prone to problems, but that is me.

Thank you so much @fingers I'm working on it now. Btw I have it in a tower 900 so there is plenty of air flow, also I keep all glass panels off for more air flow. When I was at 5.2hz my temp (even playing on Max settings on 4k) it never went over 36c . I'll give u an update once I've done what you've asked. Thanks again!

Most of the contributors in these forums are not fans (excuse the pun) of liquid cooling. A decent aftermarket heatsink/fan & properly placed case cooling fans are generally all that are needed. The fact that you've removed the glass panels plus have 13 fans tells me you don't understand the theory behind case cooling. It sure is purdy though.

Case cooling and air flow cooling are 2 different things I don't case cool because it pushes off a lot of heat thanks for the no help tho

Btw not looking for fans of water cooling I'm looking for someone that's had the same issues thanks :/

Cleared all loops cleaned water block for cpu added new thermalpaste relooped for a cleaner cycle. Ended up being 2 things my hhd was dying and causing my cpu to work harder and also my bios was out of date. Updated and changed out both and now I'm back at 5.2hz 32c thanks @fingers

1- I have never seen a dying hard drive cause the CPU to run hot. Needed replacing anyway.
2- If your BIOS was working for a year then it could have worked with the same hardware for 10 years without updating. Updating could not hurt (unless failed) but was not necessary.
3- Your overheating was probably caused by either a loosening of the thermal bond to the CPU or there was a blockage or air bubble in a water line. Since you took care of both together you may never know for sure which it was.
4- Please be civil towards those trying to help you, your comment to riider was not as nice as it should have been since you are asking volunteers for free help.
5- The proper heat management inside of your case (or any computer case) is where cool air enters low in the front of the case and as it moves back and up it warms from the components. The natural convection of the air makes it rise and expand. As long as you remove it from the top rear you are getting rid of the heat. Excess internal fans and side fans as well as open sides disrupt the natural convection and cause areas where there are eddies in the air flow which tend to heat up and not be removed efficiently. You DO want a smooth flow to gather all of the heat and take it out of the case. THIS is what riider was referring to.
** Anyway, glad you got it sorted out.
Good advice may come when least expected and may help more than some of the loudest shouting from the mountain tops.
