Intel i7 4770K Temperature

fighteeer · Jan 29, 2014

Hi guys, so i have my i7 for a few weeks now, and i don't know if my temperatures are dangerous or not.

CPU IDLE : 42-53 °C
CPU PLAYING GAMES : 59-72 °C
CPU PLAYING CS:GO : 65-75 °C

I use Zalman CNPS7X LED. Should i buy better ? and which ? about 40€ ?

fighteeer :

Those temperatures are actually quite high for the set up you are running. Now, its not dangerous temperatures, but they aren't quite where they should be. The culprit of the high temperatures should be one of a couple things here then. Either your case doesnt have good flow, OR you are using toothpaste for CPU thermal paste. If you get better thermal paste get IC Diamond, because its a lot better than the "highly acclaimed" arctic silver 5. And please tell us your case set up so that we can figure out if it works or not.

I have the same cpu with CM Hyper Evo. I don't know Zalman's cooler compared to mine but your cpu looks a bit hot. Nothing to worry about though. It's still around the Intel's recommended range (TCase 72.72C)

Ambient temps and the airflow in the case are important here. I've never seen a thermal compound effects the temperatures more than 2-3C if you don't apply it wrong in the first place. But you'd like to squeeze what you can get, so you can try some high quality thermal compounds too.

I'm currently idling around 26-28C and max of 52-53C while playing BF4. Under some stress tests it's hitting 60C and avaragin around 58-59C (ambient temp in my room is usually around 25C btw)

The thing is I was having +5-7C higher temperatures under load before adding two 120mm exhaust fans to the top of the case. They are running at 800rpm until cpu reaches 50C then I set them to speed up to 1200-1300rpm. It really helped a lot, even gpu is running 3-5C cooler now. And the power phases... They run more than 10C cooler now.

Also having Turbo Boost on is adding a bit more vcore then you'd actually need under load. I have it on too for all cores at the moment. But when I manually overclock to 4.2 GHz it runs almost at the same temp. So turbo boost is not really efficient way to keep a cpu cool. Maybe you can try disabling the setting that boost all cores to 3.9GHz (then they will boost to 3.7GHz) and see if that helps (probably it will since it will use less vcore under load this time).

But at the end of the day; consider increasing the airflow of your case first before changing the cpu cooler. If you are not satisfied with it you can buy a better cpu cooler.

My PC setup is :

Case - Evolveo G2
CPU - Intel Core i7-4770K
MB - MSI Z87-G43 GAMING - Intel Z87
RAM - Kingston HyperX Beast 8GB (2x4GB) DDR3 1600 XMP
GPU - MSI N770 TF 4GD5/OC Gaming
Paste - Cooler Master IC Value V1

I don't know if it's possible to add 1 or 2 exhaust fans to the top of your case, but like I said before, it helped me around 5-7C under load, and also keeping the mosfet area a lot more cooler than before.

Other than that you can try reapplying your thermal paste. Maybe you applied a bit much so this effects the heat transfer.

Also like I said Turbo Boost is really inefficient and for some reason increases the vcore more than that you would require, so this cause some extra heating. If these temperature values are bothering you (and i know that felling), you can try disabling the setting that boost all cores to 3.9GHz. Probably it's set to "auto" in your bios but I know that it's enabled by default on all MSI z87 mobos (since I'm using one too).

As a last resort you'd like to buy a new cooler. I can recommend Cooler Master Hyper 212Evo if you don't plan to overclock more than 4.2-4.3GHz.
