Just got my PC built and OS installed. CPU idling at 40C is that bad? + other Q

#1NOMPosted 2/1/2014 10:57:46 PM(edited)
I just finished building my PC and just got the OS installed. I will list my specs at the bottom of this post. The first thing I did was get into the BIOS and check my CPU temps. my 4770k is idling at 40 degrees Celsius, is that okay? I'm pretty sure I installed the CPU cooler right. And if it is okay, or after I've fixed the CPU issue, what than? What other stuff should I check or do? I could Google this but I feel better asking you guys than looking up some random pages on the net.

Specs:

Windows 8.1
HAF 912 case
DVD Drive
Plextor M5P Series PX-128M5Pro 2.5" 128GB SATA III MLC SSD
ASRock Fatal1ty Z87 Killer Motherboard
XFX Core Edition FX-787A-CNFC Radeon HD 7870 GHz Edition 2GB 256-Bit GDDR5 PCI Express 3.0 x16 HDCP Ready CrossFireX Support Video Card
Intel 4770k CPU
Coolermaster Hyper 212 EVO CPU Cooler
16GB RAM

In the BIOS? 40c is fine.
My 2500k usually idles at about 40c in the BIOS and every software monitoring program I've used show about 32c in Windows.

*Edit*
I have a Hyper 212 evo cooler.

Its pretty good, considering haswell runs decently hot. I have a h100i and my idle temp are around 25 it's one of the best coolers you can buy. Also idle isn't what you should worry about run prime 95 or something and test full load temperature.

40C idling isnt bad but isn't too good either.

As long as it doesn't go above 90 it should be fine.

is haha

My Haswell chip idles in the mid- to low-30s, but the BIOS always shows it in the 40s. They say Halswell runs hot, but that's about 15 less than my Wolfdale CPU could ever do.

If you really want to test and see if you have heat issues, either run Aida64 or better yet do an x264 encode. VirtualDub with x264 codec will work fine. Run Real Temp to monitor your temperatures.

Ignore any moronic advice about running Prime 95, it can potentially damage your Haswell and people who continue doing so while knowing this deserve a head kick. No need to take risks.

I've never heard this until just now. How does Prime95 destroy Haswell chips? Is it because they're not soldered on?

Prime can draw more voltage from your power supply while testing and these chips already run warm enough as is. Any extreme heat issues can obviously result in permanent damage. It's not optimized for Haswell's like Aida64 is, which also tests the newer Intel instructions that Prime doesn't.

No need to really run either program, an HD x264 video encode will push your cpu to full load and it's more of a regular usage test anyway. Intel Burn Test is another I've read to avoid because it pushes your cpu harder than any game or program ever will.

TheOtherGuy is exactly right.

I highly recommend using the Intel Extreme Tuning Utility for stress testing/overclocking/monitoring the temps on your processor. Its pushed my processor up into the 80 degree range while stressing which is more than enough for me while testing stability. I've yet to find a real world application that pushed my processor above 55 degrees so there's just really no need to push it to the brink of becoming a piece of charcoal.

Encoding X264 codec can be the same as running prime 95. The important point is to monitor to make sure it doesn't go beyond the target temperature.

The goal of running prime95 is the left it running for a long time without crashing or overheating, like 8 hours or more. If it doesn't pass that test, the setup is not suited to encode video nor doing anything CPU intensive.
