CPU 97F Idle?

[Explicy]

Hello, I recently built my PC and stuff is weird like, i have a hydro h110iGT cooler and while browsing the internet my CPU is at like 97F, and my Gpu fans are off and turn on some times while browsing on and off and both my GPUS are like 140F. Im mainly worried about the CPU. I dont think it should be this hot.

CPU: 4790K
GPU: 2x msi gtx 970s
Cooler: Corsair Hydro H110iGT
Case: Corsair 760T White
MB: MSI z97 Gaming 7

Thank you i would like to know if maybe my water block isnt placed correctly or something.

Your GTX 970s are meant to have a 0db mode( fans are off) so when they reach 60C ish, the fan will automatically kick in. The graphic card can handle 60C just fine. It is recommended to keep your gpu under 85C but it will be able to handle higher temps than that.
CPU temps are ok for when browsing but there is many variables that can affect cpu temps.
What is your idle cpu temps when you have no load on the cpu at all? What is your ambient temperature as well? Is your cpu overclocked?

I adjusted the fan speed curve on my GPUS and they now run at a steady 30 to 35C while browsing the web, but the cpu is still jumping around for 33 to 40C while idle on the computer im not sure why, I dont think this is right when i especially have a watercooling unit. It should not be getting 90-100F (Thats the Fahrenheit for ya so you can see how hot it actually is).

Also no the CPU is not overclocked it is normal with its powerboost option, so in task manager for example right now its running at 4.36Ghz with 2% Utilization running 98.2F!!!

The ambient temprature overall in the case is very cool as my case is always nice and cold and is not hot at all.

what are your ideas on this, maybe my water block isnt attached properly? Will this Damage my CPU?

What voltage it is running at? I mean these idle temps are fine really, they are not dangerous.
You can tighten the water block if it moves slightly but don't overtighten it.

normal default voltage

You realize that 98°F is only as hot as your own body? 98°C is hot, but 98°F is cool.

Ok but I bought a hydro cooler and it should be 20C idle. On bios it's 40C and on desktop with no Load it jumps from 35 to 40. At this point I'm going to buy some arctic silver and remount the block.

It can be 20°C if the room is at 10°C, but that's awfully cold unless you wear a winter coat. Most people keep their room at 23°C; the temperature in the BIOS isn't idle because the CPU is busy. Idle temperature can only be checked once the OS is loaded and all features that keep the CPU cool are active, then it will probably be no more than 10°C above ambient.

Depending on ambient, your idle of 36.1111c is fine.

Explicy,

Standard Ambient temperature is 22C, which is normal room temperature, and is more correctly the temperature measured at your computer's air intake. 22C is also a reference value for Intel’s Thermal Specifications. Knowing your Ambient temperature is important because Ambient directly affects all computer temperatures.

Here's the temperature conversions and a short scale:

Cx9/5+32=F ... or ... F-32/9x5=C ... or a change of 1C = a change of 1.8F

30.0C = 86.0F Hot
29.0C = 84.2F
28.0C = 82.4F
27.0C = 80.6F
26.0C = 78.8F Warm
25.0C = 77.0F
24.0C = 75.2F
23.0C = 73.4F
22.0C = 71.6F Standard ... or ... 22.2C = 72.0F
21.0C = 69.8F
20.0C = 68.0F
19.0C = 66.2F
18.0C = 64.4F Cool

With conventional air or liquid cooling, no temperatures can be less than or equal to Ambient.

As Ambient temperature increases, thermal headroom and overclocking potential decreases.

Here's the normal operating range for Core temperature:

80C Hot (100% Load)
75C Warm
70C Warm (Heavy Load)
60C Norm
50C Norm (Medium Load)
40C Norm
30C Cool (Idle)

Intel's Thermal Specification is "Tcase", which is CPU temperature, not Core Temperature. Tcase for the i7 4790K is 74C: http://ark.intel.com/products/80807/Intel-Core-i7-4790K-Processor-8M-Cache-up-to-4_40-GHz

Core temperature is 5C higher than CPU temperature due to the differences in sensor type, location and calibration. Tcase + 5 makes the corresponding Core temperature 79C. <-- This is your spec.

Intel desktop processors have thermal sensors for each Core, plus a sensor for the entire processor, so a Quad Core has five sensors. Heat originates within the Cores where Digital sensors measure Core temperatures. A single Analog sensor under the Cores measures overall CPU temperature.

The relationship between Core temperature and CPU temperature is not in the Thermal Specifications; it's only found in a few engineering documents. In order to get a clear perspective of processor temperatures, it's important to understand the terminology and specifications, so please read this Tom’s Sticky:
