H110i V2 isnt pumping

[FrostedAuto]

My H110i V2 pump isnt pumping. when I turn on my computer it will work for maybe a minute then it will shut off, Im getting CPU temps of up too 100C. I go to Corsair link and it says the pump is pumping at around 3000RPM but when I go to feel the pump theres no vibrations and no pumping. I have the latest Corsair Link firmware. I also downloaded Hw Monitor to make sure that corsair link wasnt giving faulty temperatures. The one thing I can think of is that instead of having the mini USB plugged into the USB header in my MoBo I have it plugged into a external one but that shouldnt matter, but to see if thats the problem Im going to get a cable that will plug into the header tmrw. Ples helpppp I realllyyy dont want my CPU to die on me.

Thanks.

280 mm H110i or 240mm H100i v2? Either way, check the coolant temp (H100i v2 Temp). Sounds like a dying unit and a high coolant temp will be the give away.

I believe that the Temp was around 50C, honestly im not sure if thats normal or not.

 

Edit: its the 240mm

Coolant temp at 50C is definitely not normal.

 

Please make sure to check how the pump is powered; see section "B" in the Liquid Cooler FAQ linked in my signature.

Contact Corsair Tech Support to start rma process. It’s probably a blockage, but the key is to let them know the coolant is 50C sitting at the desktop (or the continual slow climbing temp). That makes it a cooler problem rather than all the other possibilities.

I really don't think it is a cooler problem tho, I feel the air blowing through the radiator and its cool air, however the pump isn't pumping so I think that when it measures the temp of the water it measures it at the pump where the water is hottest and is not flowing.

[c-attack]

Precisely. Blockage = no flow. The cold air coming off the radiator while the coolant temp reads halfway to boiling is the nail in the coffin. Make sure to include that in your support ticket.

[FrostedAuto]

Okay, makes sense. Thanks for the help fr.

Actually I just remembered why I didn't think it was a blockage, when I first turn on the computer it works for like a minute.

What normally happens in these situations is the cooler is unable to transport or release heat to the radiator because of a flow obstruction. Most blockages occur near the pump, although that is not a certainty. At that point, you basically have a tea kettle. The coolant starts off at room temp before you hit the power button, then heat starts to build. If the pump were completely off with zero flow, you might get 30-90 seconds before hitting max and a forced shutdown. With partial blockages and non-pump failure, some coolant is getting through - just not nearly enough. Over time, you can watch your CPU temp (and coolant temp) tick upwards... 35...40...45...50...55.. 75..80.. etc. until you reach the shutdown point. That could take 5 minutes or one hour, depending on the level of the blockage. Regardless, a partial blockage usually gets worse, so the time to act is immediate.

HEY! I fixed it! I opened it up and drained the cooling water and put in distilled water, now it works fine, ik its supposed to be a closed system but whatever, at least it works now.

I guess as long as you “closed it”. These things don’t go back together well, there is no fill point, and you will need to be checking for leaks daily. Be careful.
