H105 pump not starting after waking from sleep.

Hello LinusTechTips Community!

 

I have a slight problem with my new (ish) Corsair H105. Whenever I wake the computer from sleep mode, I notice CPU temperatures slowly rise from 25C (normal idle) to over 60C. (I have not seen it go higher because i always shut the computer down before it heats up even more.) After the restart, it works just fine. I also notice that the white light on the pump body also does not illuminate after waking from sleep. 

 

I am running on the Gigabyte GA-H97-D3H motherboard, with the pump in the CPU-OPT fan header, and the two fans stock with the cooler in the CPU-Fan header. All fans have been slowed down as much as possible in the BIOS to keep it quiet, and I have no OS level fan controllers. 

 

Can anyone help with this issue? I have not found any answers anywhere else. 

Thanks

 

PS: I would prefer that any solutions do not require the radiator to be taken out, because the way I have had to mount it, I have to take the whole case apart to get it out.

 

 

Here is a screenshot of the temperature rise...

Is the radiator pump header set to Auto?

[PCGamer1138]

No. All fans are set to Manual - 0.75 PWM Value.

While in the BIOS, the pump header is reading a value of 1090 RPM, and the Rad fans at ~900 RPM

You should have the pump connected to the power supply with a 12v adapter. It's best for it to have constant power. Sometimes the header on boards don't work properly.

Thanks. Is there anything i might be able to do to get it working properly on the headers?

Switch the pump header to a different header, one that orovides provides voltage control. The CPU OPT header is mirroring the primary CPU fan header, and thus may not be providing enough of a start up boost for the voltage controlled pump when waking up from sleep.
