H100i 90c WTF?

[Manos]

Okey i got a h100i for 2 years now and i slowly watched my temps rising as the timed passed today i tried to switch thermal compound and in the prime 95 test i got 89c constant temperature at 4 minutes running time with 20c room temperature. i remember when i got it first with prime was getting 55c i cant underastnd what is going on.. i tested my older cooler 212 and i got 75c max with prime. I got an i5 4690 no overclock and nothing is blocking my airflow...

Sounds like the pump on it could be dying, does it make any strange sounds, or any sound at all?

[Manos]

well i never heard any noise before and nether now... the corsair link shows it at 2188 rpm

That pump speed is a bit low I always recommend a pump speed of 4000RPM upwards

Your joking right?

i cant raise it from the software ithink that is locked

My H55 runs fine at 1400

Go into the BIOS and change speed on there.

Bios doesn't change pump speed? Atleast none ive ever owned.

A faster pump speed means the heated liquid has less time to dissipate the heat so therefore the CPU doesn't heat up as much.

yup i think the same

If it's a variable speed pump, you can possibly change it through voltage or PWM within the BIOS. I don't think that the H100i has one though.

I've set my H60 the BIOS.

From what I remember, the H60 doesn't have a variable speed pump, so you are either damaging the pump, or putting it under stress.

Most run around 1.5-2k and 3kish in performance mode. 4K would both be loud and hot from the extra voltage needed but i could be wrong.. I think he's trolling or just doesn't no what he's talkn bout.

It was about 2000RPM out of the box and every time I do a fan speed reset in Asus Ai Suite 3 it always resets. 

[Manos]

well i dont think that is the pump becaue i have never tempered the speed...

As it should because it's being treated as a fan. But it doesn't change what I said.

I can defiantly change it.

I'm not denying that, but you shouldn't be because it's not using a variable speed pump. It should be running at full speed constantly.

OP: This might sound stupid but if i'd be you I'd check if my radiator isn't full of dust. A bad airflow trough your rad could be a cause of the heat not dissipating. Also consider making sure your fans are running properly (we'd assume you did that already) and make sure thermal paste was applied properly last time you changed it (We'd also assume that you know how to apply thermal paste).

 

So if the airflow on your radiator isn't a problem (fans running properly and no dust in it) and thermal paste was applied properly I'd also assume that your pump might start to suffer some issues.

 

Another extremely rare case scenario would be that your ambient temps (Inside the chasis) would be extremely high for an unknown reason and therefore not dissipating the heat in the radiator properly. This is highly unlikely though....

 

Best regards!

In my experience, a h100i without any fans running was enough to keep a 3570K@4.2GHz under 75C under gaming so yah know...

 

What are the idle temps and gaming temps? Prime95 isn't always the best for getting normal operational temps
