I have a 4790k, Asus Z97 Pro, and Hyper 212 Evo in my PC
It idles around 35C, which I found to be normal.
I have 3 intake, 3 exhaust fans, and 2 on the cooler itself in a push and pull comfig, all of them good quality fans and running 1200-2000RPM

Playing BF4 (my most CPU demanding game) I run between 58-70C on my cores, and more importantly, on my IHS (package) temperatures.
4790k should not get its ihs hotter than 72C if I remember right, and My PC somewhere told me (I think it was in AI Suite 3 or in my UEFI Bios themselves, which I have yet to delve into) Thet my PC will throttle or emergency shutoff at 76C on the ihs or the cores

I'd ideally like it around 60C max, but the CPU currently ran Prime 95 for only 40seconds, and hit 74C...
This is with the CPU ALL STOCK with only 40x multiplier, 44x with turbo, the voltage only ever hits 1.211V
How can I be hitting the chips max temperatures with my Hyper 212 Evo?
Would a better cooelr help or? all I could do is get an AIO cooler, which I dont want to do, I just wasnt to run it stock safely -_-
It sounds like even the stock cooler is doing a better job right now than my Hyper 212 Evo...
Yet I talked to someone running 4.7ghz with a full 1.275v running it at 60C while gaming in BF4.

I use MX-2 thermal paste, which is cooler on average than even Arctic Silver 5, and I used a pea size dot in the center of the die, dropped the cooler on, tightened it...
It should be fully set up now, its been a week, but I get the same temperatures.
I also hear horror stories of people who end up getting an AIO or High end air cooler, who still get the same temperatures. Right now while I game, my cooler is cool to the touch, yet the CPU is reading almost 70C in just gaming
Is the Intel TIM inside bad? I don't thik RMA will help, since I talked to another who fully RMA's, and the next ran exactly the same. Also, I don't want to Delid just to run the CPU stock...
What should I do? I wanted to run it at 4.6ghz or so on like 1.25v or less, which is entirely feasible, but not with the temperatures I'm currently getting.

From what I've read, AIO water coolers are only worth it if you go for something top-of-the-range, like an H100i. Entry and mid-level water coolers don't really offer much of an improvement over a good air cooler, and are more expensive and nosiy to boot.

The cooler you need depends on how much of an overclock (if any) you want to achieve. A Noctua NH-D15 or NH-D14 would be a good match for your 4790k if you aren't keen on water.

The first thing I'd do is reapply the thermal paste. Instead of a central dot with the cooler placed on top, make sure the paste is spread evenly across the processor's entire surface. As you probably know, thermal paste acts as a heat transfer, so you want to ensure that the entire surface area is covered.

Yes, but many review sites and experts recommend you just drop the cooler on top of the dot, so it evenly spreads out across the Die of the CPU as it gets hot the first few hours, that way the paste is properly dispersed to where it gets hottest. About 80% of a CPU's Heat is drop dead in the center of the CPU's IHS anyways.

I will have to reapply it, but I'm pretty sure its on there properly now, and I talk to others who have tried all these methods of remounting (Dot method, X-method, smearing method, line method), and it runs the same every time for them : / and those guys had Noctua D14's... Which was my next option if remounting doesn't fix it, but they said they only saw a 2-3C difference from the hyper 212 Evo

Do you have experience with Haswell's Temperatures? does this look abnormal?

I do have a 212 Evo, but on a 2500k. I've not used Haswell myself but I've heard that they can get hot very easily.

Being in the 70C region with that processor and a 212 Evo doesn't sound that abnormal. To give some perspective, I'm getting the same temperature on my 2500k at 4.2Ghz. A 212 Evo is a good cooler, but it's typically used for overclocking processors that start in the 3.4Ghz region. Given your processor's Turbo Boost of 4.4Ghz and the heat issue with Haswell, a better cooler could be on the cards if the new thermal paste doesn't do the trick.

That said, I do wonder how the hell the stock cooler can cope.

Hmm... I got SO many fans too :p entire case covered in fans costing $15-25 each...
Think I should look to the Noctua D14 then if temps don't drop? I have a processor with about another .1ghz potential over the 4770k, and I just want it stable under 60C while I play BF... Benchmarks will ALWAYS drive it up higher.. If I had kept running Prime 95, no doubts I bet it could have hit 87C...
Even then, Asus Suite Auto Oc'd my Processor to 1.29v at a full 4.8ghz... it was STABLE... but idled at around 52C... load in even low end game I was hitting 75C... couldn't handle that...

So much processor potential, why choke it with a horrible cooler ya know : / Gonna have it for a while, may as well OC right off that bat and enjoy its full potential.

Totally agree, a processor like the 4790k is certainly deserving of a better cooler. The NH-D14 or NH-D15 is arguably the best air cooler on the market, it's just a shame that Noctua don't make it more aesthetically pleasing.

I guess you could disable Turbo Boost so the clock speed stays at 4Ghz, but that seems rather moot. Like you said, why choke the performance of a top-of-the-line processor?

It is very important to know what's going on underneath the heat sink, I further bicycle_repair_man's suggestion by also suggesting you pull the heat sink and inspect the thermal footprint under it, many go on suggested application methods and never check to see what that application method did under clamping pressure.

With thermal compound you're after the least amount you can possibly use and attain full coverage, you do not want a thick goopy layer that squishes out all around the IHS.

Actually for a CMH212EVO your temperatures look normal, your thermal compound application could be affecting the coolers efficiency either plus or minus 1c ~ 2c, maybe, but the CMH212EVO can only do so much, that's why it is cheaper than the best Cooler Master considers the top of their line of their own coolers.

So, what cooler would you recommend. I don't really like AIO coolers, Especially since I see $70 Noctua D-14 MATCHING or almost matching the H100 so...
Also, is it safe for me to run at these temperatures stock? Is there any throttling at these temps (usually gets to around 68C in gaming) or is it hurting my performance/CPU life.

Also Also,would it be worth it to switch to a Phantek or Noctua, or would it only realy lower me another 5C? I HATE spending money on this that don't make my PC faster... a nice $50-70 Air cooler is much preferred over an AIO or closed wate loop that cost $100+ hense my "I just want it cool enough" attitude. I don't mind the fan noise, in fact even with 8 case fans right now, I can't HEAR my PC... All I hear is my Corsair's PSU Fan (which is annoyingly loud -_-) and they're all at 1250RPM+...

This "Air cooling is loud" is a myth, people just buy shitty fans. (kinda ironic I spent $15-$20 on each fan, but don't wanna pay for a heatsink...they obviously aren't doing me much good...)

Hmm... I'll have to look into it... I see that they get REALLY close the the H100i, and beat the H100, beat the H80 by almost 15C 0_0

Think I'll look into that
Thanks for the help
