H80i/H100i Hot coolant issue over time [FIXED]

[SnakeWildlife]

So my processor (AMD FX 8150 3.6ghz) when idle sits around 40'c when it used to be around 10'c (I live in a cold place), and under pressure used to be around 40'c but now goes to 85+'c (getting too hot) and then causes system shutdown.

Iv cleaned out my radiator on the H80i and reapplied thermal paste and that didnt really change much. A temporary solution is that i now underclock my CPU to 70% and it goes back to near enough the old temperatures (cant really play games though when you underclock that much), and then i noticed something unusual about my hardware temps. They were taking a while to cool down.

My 3 year old H80i is reporting that the Temperature around the block is 40'c when the processor reports at 20'c, it appears that my coolant has become hotter than the processor, thus heats it up rather than cools it down when i stress test or play a heavy game.

Iv checked all the fans are spinning and the pump is in fully working order (i gave it a good bit of maintenance) but yet the coolant seems to slowly warm up but takes far more time (like 30 minutes) to cool down back to idle temps.

My question is, has anyone else had this issue?
I cannot tamper with the coolant liquid itself yet the coolant liquid 'appears' to be the culprit, thus i have no idea what to do about this.

(''buy another one'' is not a solution, im interesting in fixing this rather than spending big bux)
-------
UPDATE 6th May 2017
I have found my solution! I'll leave it here incase anyone in the future has the same issue.

Turns out that one pipe was cool and the other was very hot <this is something you should check if you think your pump is faulty, and even though CorsairLink software reported that my pump was still pumping at around 2250 rpm, the pump was in reality NOT working and the software only displays what the pump is 'attempting' to do.

It is a 4 year old H80i that i own and the 5 year Warranty applies to ANYONE wherever you bought it. Corsair accepted my RMA request and are sending me a replacement free-of-charge, not only that, but are giving me the NEW V2 version (circular cooling block) of the H80i and not the old original one. So technically im getting a little upgrade there as the new version can cut another 2 degree's off of temps.

So to anyone having cooling issues with the H80i, (it still is an amazing cooler btw 10/10) if you find that one of your pipes is cool and the other one is really hot, thats the proof you need to confirm that the pump is failing and not pushing the liquid through as it should.

When the pump is working correctly, both pipes should be pretty cool. One pipe will obviously be warmer than the other, but if its really hot (feels around 45'c or hotter when you touch the pipe with your fingers) then this will confirm to you that the heat is not being dissapated as it should.

Hopefully other people who have the same issue i have, will find the above information useful.

Get another one/RMA is not a solution.

Also, i am not covered because of their Warranty terms and conditions:
"""Exclusions

In liquid cooling, replacing the coolant is a normal task to do overtime. Typically recommended to replace coolant every 6 to 12 months.

Coolant gets old. Since you cannot change the coolant in a sealed AIO cooler, you are about out of luck. I know you didn't want to hear this solution... but... get another one. Or better yet, get into actual liquid cooling. I wouldn't trust an AIO cooler to last too much longer over a year or so, before degradation really starts to be noticable.

why not? most of these coolers are sealed..so repairing them is not an option most of the time,,

unless your cooler looks like its been to hell and back, your still under warranty..at least try and file an rma..if you do get a new cooler, chances are it will be an new and updated version of your older cooler, so why not.

Sounds like the pump is faulty; not working at the correct RPMs; causing the liquid to get too hot due to lack of flow.

An H75 with Push+Pull fan config can keep a 9590 under 50*C at all times when under full loads (or at least high loads in demanding games); so yea obviously something wrong with either your AIO or your fans/airflow setup.

That's very weird, so your warranty is only covered if you don't use it? That makes no sense to me and what's the point of any Corsair warranty if that's the case?

[chiefputsilao✖️ping]

i think the OP should contact/email corsair customer support to get clarification.
this way, OP will get definitive answer whether to rma his cooler or start looking for a more reliable cooler brand.

[Bad 💀 Motha]

Yes talk to Corsair Support; most likely they will RMA replace it.
Don't look and go "No I doubt they will" you do not know this.
Seriously, complain in a calm, collective manner.

Keep a finger on the radiator when it's cold, to see how quickly it heats up. If it takes a while, your diagnosis of the pump being in working order is faulty.

UPDATED [FIXED] I have found the solution to my problems, and have left information for others in the Original Post. Remember: Just because CorsairLink reports that the Pump is working at 2250 rpm (or whatever rpm its running at for you) DOESNT mean that it's actually pumping at all, the software only reports what the hardware is ATTEMPING to achieve, it can never record if its actually WORKING.

so the pump is dead. go and rma it then.

you just stated that the pump wasnt working...nontheless hope you receive a speedy rma.

He did state it.

To OP, glad to hear that you're getting a replacement! Corsair is pretty good with their worldwide warranties.

Always doubt the software readout when there's clearly something wrong. Pumps make noise, they create pressure in the tubes, and they move the heat around. All three can be manually verified.

Snake Wildlife eredeti hozzászólása:

There's such a thing as a flow sensor, that can measure it perfectly fine. Of course, that adds to the cost of the unit while a failed pump is a rare, and not much of a hazard. Cheaper to just offer a replacement.
