Water Cooled Temps

[Slim Nelson]

Hey guys, just a quick question on water cooled cpu temps.

Is it possible for my cpu temps to be lower than room temp while it is water cooled?

I have a Xspc custom water loop on my amd fx 8350 and it shows 16c-25c most the time according to cpuid hwmonitor and speccy, I've checked using other tools like occt and prime95 (not while stress testing) and shows the same thing. Room temp is around 27c usually and there are times it goes above that of course but most the time like right now, it sits at like 18c..

I don't see how it'd be possible unless the water was cooled in the reservoir or something.

It is not possible unless there were something like antimatter on your CPU. It is probably the bios version you have. It may be using the wrong multiplier when reading the ADC (analog to digital converter) causing the value to be lower by a factor. Try updating bios.

No it is not. What are you looking at, cpu package temp? Its wrong and only becomes somewhat accurate when things start getting hot amd cpu's are known for their terrible temp monitoring, I have the same problem. When looking for temps at idle either go into your bios and look or you have to use the cpu temp the motherboard records, its in the motherboard section of hwmonitor i believe.

My bios was out of date. I just updated it. Readings are still off though. I think it might be like Dunlop said and it's just AMD processors. I've had this problem with AMD processors before.

Yeah, package temps I believe. I went into bios and it reads correctly in there though, says 36c.

Yeah package temp is usually wrong at lower temps for some reason. If you put the cpu under load and get it hot it starts reading close to the right temp, in about the 50c and up range.
