H150i 360mm High Coolant Temperatures


Recommended Posts

I have already made a support ticket so just waiting to hear back, but wanting to see if anyone else has had any issues

 

I have had the cooler installed for about 2 and a half months and now upon playing some games I have my coolant temperature increasing to 60c which is triggering the built in fail-safe of the AIO

 

I can't really find anything about what the coolant temperatures should be doing too, the cooler sits around 40c just browsing now, turning on the system it starts at about 25c

 

Anyone got any tips on what I should be doing?

do you have speed readings on the fans and pump?

If the pump is indeed spinning, when you touch the tubes, can you feel a big temperature difference between them?

 

It sounds like a blockage, but having that occur after 2 months is very weird. Usually it's a pump that doesn't spin, a blockage due to residue buildup, or a kinked pipe.

 

Usually, ideally, the coolant wouldn't rise past 40°C, or not far beyond if your case has bad airflow. temps in the low 30s at idle would be pretty typical too.

Fans are at 1550 rpm and pump is at 2600 as I have them on the extreme preset, no real difference between the pump and the tubes

 

Corsair just got back to me saying to RMA the product, so I guess I might just do that, wasn't asked to troubleshoot or anything

I have my coolant temperature increasing to 60c...

 

That's because this is so far out of the expected range there isn't any other possible cause aside from the blockage. It needs to be replaced and is adding 30-35C to your CPU temps at all times.

Hi, I'm having a similar problem here. However this is brand new h150 aio. I first notice it when testing all the fan and aio, not mounted on anything and the liquid is already at 40c+. I then mount it on 5900x. Cpu Temp is similar to my 360 galahad. Water temp does seem to fluctuate a bit but never below 40c. Room temp is 30c. What's your thought?

Did a few test. Run 5 r20 straight cpu Temp won't go beyond 77c with room temp of 25c and package power of 173w. Coolant temp is... Weird. Always mid 40ish. For once it's 50c and my cpu idling at 40ish.

This is concerning since sitting on the desk with no heat input the coolant temp should read effectively the same as the room temperature. The cooler is obviously working or you would not be able to get the Cinebench test results you did and those are right at expectations. It suggests there is a problem with the sensor itself. Maybe it is not exactly in the right position, touching something else, etc., but all of those problems are not fixable on your end. I would contact Corsair Support.

 

Make sure you are not running other monitoring software like AIDA or HWiNFO while assessing this. The programs usually conflict fighting for access to the hardware and garbage data is the normal result. However, the value are usually so absurd there is no question something is wrong (216C, -17C). It is not usually a small positive or negative offset to the value.
