So I have a Kaby lake i7 7700k and I have a corsair h60 and my idle temp is around 42 is that normal? Also the pump rpm is at 4000+.is there software I need to download or something I need to change in bios

Figure idle temp on a smaller aio is usually somewhere around 10-13°C above your ambient temp, depending also on airflow, just how soon you tested after heating up the case with the gpu, if the radiator is sole exhaust etc, so it's entirely possible to see a 20°C above normal ambient temps. Also must take into consideration that an air cooler will return to minimal temps very fast, whereas liquids don't, so if you test the cpu too soon after running extensive heat, the liquid will be hotter than normal, which lowers its ability to absorb heat energy as fast. And, of course, in Windows 10 there's Always junk running in the background, so a true (less than 5%cpu usage) idle temp is getting quite hard to get. So 40°C ish, isn't uncommon...

datread2000,

On behalf of Tom's Moderator Team, welcome aboard!

Idle temperatures depend greatly upon ambient room temperature, and whether "idle" is really idle, which means 1% CPU Utilization in Windows Task Manager. Further, CPU temperature in BIOS is higher than in Windows at idle, because BIOS boots the processor without power saving features and at higher Core voltages to ensure that it will initialize under any conditions.

Here's the operating range for Core temperature:

Core temperatures above 85°C aren't recommended.

Core temperatures increase and decrease with ambient temperature.

Highest Core temperatures occur during stress tests, rendering or transcoding, but are lower during less processor intensive workloads such as applications and gaming. Core temperatures vary greatly between games as CPU workloads differ. Idle temperatures below 25°C are generally due to ambient temperatures below 22°C.

Q: What is your ambient temperature?

With respect to Gahl1k's suggestion, CPU-Z and EVGA PrecisionX do not monitor Core temperatures. For simplicity, I recommend the excellent utility "Core Temp" - http://www.alcpu.com/CoreTemp

If you prefer very detailed monitoring of all hardware functions, then I recommend "Hardware Info" - https://www.hwinfo.com/download.php

Also, you might want to read this Sticky: Intel Temperature Guide - http://www.tomshardware.com/forum/id-1800828/intel-temperature-guide.html

Once again, welcome aboard!

So 40°C ish, isn't uncommon for that particular cpu, which can rub warm anyways. So you are good there.

Yes, 4000± rpm is normal for that pump as it's designed to run flat out 12v constant. Trying to lower or vary speeds can damage the mechanism, and/or even raise temps, either at idle or load.

Personally, I prefer RealTemp over CoreTemp. It's just as accurate and easy to use for Intel cpu's, but was also written in conjunction with the use of Prime95 and has no issues with multiple core readings and gpu, all of which can be stuck in the task bar for easy viewing.
