H115i Pump Life..

Recommended Posts

I leave my computer on 24/7/365. Lately I noticed my idle temperatures for my Threadripper have been idling about 50C, which is unusual. Fan speeds were noisy. Looking back about 5 months ago, the temperatures during idle were about 29C<->32C with a air temperature of 70F. (I graph everything with rrdtool etc)

 

I examined the CPU block and i squeezed the tube, and I heard some bubbling noises. The temperature started to drop and the fan speed decreased as well.

 

I'm becoming worried that my CPU pump is going to fail very soon.

 

What is the life of the pump? I cannot find a MTBF anywhere, and if my suspicion is correct it will be failing within the next few months.

It’s not the pump that is failing, but you’ll need to replace the unit all the same. You’ve got a partial blockage forming preventing the coolant from circulating at the proper rate. Squeeze the tube, pressurize more coolant through momentarily, but that isn’t a permanent solution. Contact Corsair Tech Support to start the RMA process.

RMA is also not a permanent solution.

Same Problem for me with different liquid coolers, the have a Problem with Evaporation over time (or leakage over time), so the AiO liquid coolers can't work forever.

The pump would work for some years, but without liquid the heat-transportation won't work.

(My H60 and H90 already are no longer useable because of this and for my H115i I don't know how long it will go on working fine after using it for around a year, 3 Hours at workdays, around 10 Hours at Weekend / Holidays)

This is not the same problem you described in your thread. Unfortunately, the above issue is a little too common on that model and that is something that should not happen quite so easily. If this is happening to your cooler, I also suggest a replacement, but we can continue that discussion in your thread.

when the heat goes up, you have a Problem with transporting it.

It can be the pump, but more common, and specially when you get it to work better by squeezing one of the tubes, you have a Problem with missing liquid.

As you described in my thread, the Evaporation (or "leakage" as I have described it) happens over time.

In this case, the AiO Cooler runs 24/7, always having higher temperatures (no time to get back to room-temperature), the liquid has more time and Options to evaporate.

His H115i seems to have reached the Limit where the remaining liquid won't be enough anymore.

 

Question to Monkburger:

where have you mounted the Radiator?

At the Top or on a side (front)?

Top of my case (TT Core7 cube case)

 

I'm RMA'ing it. Hopefully the replacement will last. I bought a Noctuna Cooler in the meantime. Right now it's idling at 59C with the pump at 3100RPM... if my math is right, it will completely fail in less than 6 weeks.

 

The H55 I have is still running solid in another computer, 4.5 years later.
