Noob AIO question

[pstarlord]

I've got a Kraken X62, and in the CAM software there are fan options for the fan and the pump.  They have options of Liquid, CPU and GPU.  Since it's the cooler for the CPU I assume that I'd want to use the CPU temp to set the fan curve.  Right?  Or is there an advantage to using the heat of the liquid inside the cooler to set the fan curve.  I assume the "liquid" setting would be the head of the liquid in the AIO anyway, please correct me if I'm wrong.

 

Thanks!

Yes, you’re right about the liquid temps, and no, there is no advantage to it. The liquid in the loop takes time to heat up, so if you’re CPU gets a sudden intense workload, the fans won’t start spinning up until several minutes later when the water starts to warm up.

 

(yes we can argue the diminishing returns of fan speed vs CPU temps for water cooling all day, but to a point, it’s better that your fans ramp up. Not here to discuss that lol just answering his question)

CAM is a bit of a shit software IMHO. Liquid option would be the speed of the pump. Fan obviously the fan speed, GPU is irrelevant unless you have a loop/Aio on your graphics card.

 

Fan speed to CPU temp is probably best, but the thermal mass of the water, rad, pump etc will take the hit of any CPU load.....I have mine set to silent. Pushing more air through the rad will only increase noise when you have high loads on the CPU, the extra fan speed will only make a difference after the entire loop has heated up.

the liquid temp reading is only useful in checking cooler's mounting. If it's good, then liquid temperature goes up. If it sucks, then liquid temperature doesnt go anywhere.

Thanks for the quick replies!  This all came about because somehow, probably due to me tinkering with something and forgetting about it, the Pump and Fan got set to GPU.  It wasn't making much of a difference, but my overclock became unstable.  I know I have my Ryzen 1700x pushed pretty hard, running at 4.1GHz, but it's passed every stress test I could throw at it.  And today, it couldn't get through a Cinebench run, unless I dropped my overclock down to 4GHz.  

 

I did a few cinebench tests just to see and here's the results if anyone is interested. 

 

Ryzen 1700X Overclocked to 4.1GHz, at 1.425V

 

Both Set to GPU = Crashes  Drop OC down to 4.0GHz, completes Cinebench with a 1719 score

Pump set to Liquid, Fan set to CPU =  Successfully completes multiple runs, OC at 4.1GHz with scores of 1753 and 1741

Both Set to CPU = Crashes multiple times on 4.1GHz OC.

I honestly think CAM is useless except for the RGB options for the CPU block. I've had my 4790k clocked to 4.8GHz for over a year without touching that software and the temps have been fine. Reinstalled it the other day funnily enough (to match my GPU RGB for a party) and it make no difference to temps whatever the pump and fans are set to.

Air is still better and consistent on temps

Not what I asked, but thanks for playing.

Have you tried pump at a fixed rpm (usually max speed) and fans on liquid temperature? This is usually the logical setting for typical aios.

I have not, but I will certainly give that a try.  Thank you very much!
