Water Cooling issue

[abz123]

Hey Guys,

First post and semi noob here.

I purchased my first second hand gaming PC recently from a friend of a friend.
Specs;
i7 2600k, OC 'd to 3.8
rog maximus formula V (full north+south bridge water cooled sandy bridge),
msi gtx 770,
650w psu,
120gb ssd,
1tb hdd, full case,
16gb g skill ram.
Liquid aio cooler
5 fans.

At first it was working with no issues and then I decided to overclock the CPU by a little bit from 3.4 to 3.8 with no issues at all. However, I'm having an issue now where the liquid cooling is not working. Its sporadic. Example of this, I turn on my PC and start navigating around and notice my core temps are going up steadily and eventually hit 90 and the PC turns off. I reboot and get CPU temp error F1 to load bios settings, from here i usually just restart the PC and then the water cooling starts working again. Other times I start my PC, water cooling systemis notworking and after 5-10mins all of a sudden It turns on and core temps come down to 25-30 degrees and it runs flawless. Keep in mind this is all new to me and i'm not sure where to look or even start. Going to list some stuff i've tried/noticed.

fans connected to the water cooling system are working fine
connected to 4pin molex directly to PSU
is it being throttled?
can I damage my motherboard if the temps hit 90+ degrees? Usually this happens and the PC will turn off immediately


I can provide any additional information on request..

Any help will be greatly appreciated.

Is the pump running when this happens? Do you have a way to tell?

Loop might be blocked or have air bubble in it....when this happens does tubing from CPU get warm/hot.

In theory CPU will throttle and save itself but I would sort this asap...not good for the CPU in the long run...

What AIO cooler is that? original tubing?

Not sure how to tell if the pump is running. Only way I know its working is when I can hear the fluid moving.

Tubing does not get warm or hot.

Yes, want to get this fixed ASAP.

Unsure.

Thanks for your help.

You should not be able to hear the fluid moving, hearing a hum from the pump is fine but if the noise is more like water moving or the swish of water then you have most likely got an air lock. Is there a reservoir to your system or some way to top it up? You should try tilting the case to free the trapped air. It's also good to stop the system for a while to allow the trapped air bubbles to group.

FYI my pump is the h220 and it appears it has issues from the get go. I will be replacing my pump ASAP.

This is what happened to me with the swiftech 220. I could hear the water swishing around and was wondering what the problem was. I am glad i read this thread now as i have just learnt something.

Yes, if you can hear liquid moving it means you have air in the loop and in a closed loop system this means you have a leak (slow/fast) probably best to replace the AIO cooler...

That is a Swiftech that someone replaced the tubing and added the VRM block into the loop, I believe there may be a plug on the radiator to add, drain water, but I am not sure of that
Don't worry about adding the VRM block into to the loop if you replace with another AIO, it shouldn't be needed unless you are overclocking a lot higher than you are now
you could also add a reservoir in the loop but you will be better off replacing the complete unit

thanks guys,

Will be replacing the full setup with corsair h100
