i7-4790k running too hot?

Never really watched my temps (much), until I started to get some new fans for my case.

My i7-4790k is running at around 33c at idle / youtube watching kinda loads. It does not have any OC currently.

 

When running an Aida64 Stress test to check the new fans, it instantly jumped to 80-85 degrees. Even on FULL BLAST fans (set to 100% for the test).

I still did not think this was that bad, since it is a stress test after all, but my wife also got a new case + fans. And her CPU never runs hotter than 62c. Even on full blast + maximum OC (i5-3450 only, but clocked to the limit of x39)

 

This got me thinking: Is my i7 running too hot?

Specs are:

  • i7-4790k
  • Glorious 212 cooler with 2 fans (one that came with the cooler, added a Noctua 120mm to the mix (80ish cfm, 2.6mm air pressure)
  • Front intake 2 Pantheks 140mm fans
  • Exhaust 1 Pantheks 140mm fan
  • Fractal Design R4 case (replaced the stock fans with those mentioned pantheks and added a second front intake)

 

Note:

My idle temp went from 40-45c ish, down to 31-33c when adding the new fans. But the temps under stress still got me worried.

Is my wives i5-3450 really that much cooler? She has less cooling in total, but still has a 20-25c delta over my machine. It just does not feel right. Was considering changing thermal paste, but wanted to check for input here first.

Haswell uses a FIVR inside the CPU to generate the CPU core voltage, while Ivy Bridge doesnt. and relies on the motherboard for that. That's why Haswell generates this much more heat.

So these extreme deltas are actually legit down to the architecture? Crazy.

to some extent also the cooler, Hyper 212 is as little as you can go above a stock cooler to be worth consider buying.

I see. Thanks for your input! :-)

 

My next case / CPU / cooler will be quite a bit beefier. Got this rig when I was still in university and 1600 bucks was a lot of money. So I had to cut some corners somewhere. Kinda figured case fans and cooler would be two of those corners and this may prove that right.

Your CPU cooler is lacking. That'd be one.

You're also running a stress test. It's right in the wording. Of course it's going to sky rocket temps.

Your idle temps are fine.

 

Something you really have to consider that everyone forgets, is the ambient temperature of the room. It'll alter whatever results you get when you compare it to benchmarks others have done.

What are you overclocked to? Surely this isn't at stock, as my 4790k managed 4.7 all core with the 212 Evo, maxing out at 65 Celsius after long stress tests.

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

How many watts do I need? ATX 3.0 & PCIe 5.0 spec, PSU misconceptions, protections explained, group reg is bad

Well, it is stock right now. As I said in the OP. Your numbers don't align with like a dozen topics I have been looking at in the past hour tho. People usually hit 80+ degree with 4.6+ on better coolers. Given that stock is like 4.4k anyways, I am not that far off. At least when checking whatever I can find via google. 

 

You are the first to claim this kinda low temperatures for 4.7.

Well, seems like the info that i7-4790k has way too much voltage was right.

Downloaded Intel Extreme Tuning, OCed slightly to 4.5 and changed the voltage offset to negative 0.070.

 

Now i am getting 77c max on all fans set to 25% (cpu) and 50% (case). Now that is a pretty damn big step in the right direction. Noise levels went down to like nothing. And I get a minor OC anyways.

That is some serious voltage headroom right there. Did not expect that for sure.

I've been told I have a gold sample but I still pushed the limits, and the hyper 212 should be more than enough for stock. Good to hear you got that OC and improved temps.

33 degrees at idle is pretty hot. Do you have air conditioning? Is it enclosed inside a desk or up against a wall? I thought my 28C was a high idle temp with 24C ambient air. 

 

You're overclocking with a hyper 212 and have the fans at 25%? Personally, I run all my fans at 44% idle and then curve gpu and cpu fans based on usage up to 100%. Noctua fans are near silent, to me, under 46%.  

 

Get a Noctua cooler, bump up your fan rpm, replace the thermal paste with the included stuff and call it good.

 

If you want to go hardcore, delid your cpu and replace the ihs with liquid metal(watch many youtube videos before attempting).

What's your core voltage set to?

If you ever need help with a build, read the following before posting: http://linustechtips.com/main/topic/3061-build-plan-thread-recommendations-please-read-before-posting/

Adaptive with an offset of -0.070 now. 

This setting allowed me to go from 100% fan speed to 25-50% fan speed while improving temps by 5-10c.

At full blast the temps are down to 65c, but the noise is kinda annoying at that speed obviously. ;-)

212 is enough to that CPU, even with average OC running (done and tested). No need to get anything bigger for just stock clocks and manual volts. Change of paste after few years in use is always good practice.
