Currently installed an i7 4770k processor on my ASROCK z87 Extreme4 motherboard, alongside my R9 290, and I have just tried Battlefield 4 on ultra settings, the frame rate is brilliant but my cpu is hitting ridiculous temperatures!! I really don't think this is safe or supposed to happen either. It's only on the stock fan but even then it seems way too extensive! Suggestions?

Edit:Thanks for all of the responses! And im currently using a HAF XM cooler master case, its massive and i deliberatly bought it for the airflow. I have one 200mm intake fan on the front, one 200mm intake on the top, next to another 200 mm exhaust fan. Two 140mm intake fans on the side facing directly onto my gpu, and one 140mm exhaust fan on the rear. The psu is also using the bottom to intake air to cool itself. So altogether thats 6 fans and it still seems too ridiculous?

Thanks, Adam.

The stock cooler is usually fine if you aren't overclocking, not good if you are. You haven't given much info on your case and case fan configuration, but air flow is critical. You have a Z87 board and an unlocked processor, I would recommend getting a third party cooler.

I suspect barbernet_1 is right.

As a test, take the side of your case off and monitor the temps while gaming. If that's more acceptable then it suggests the 290 is turning your case into an oven. If that's the case, don't just chuck extra fans in haphazardly, google case airflow, check out a few guide and make sure you're planning it properly.

You didn't accidentally install one of your case fans in the wrong direction (intake/exhaust) did you? It's pretty easy to do!

Correct. Also since you have a 4770K processor, it is overclockable. If you want to overclock you need a good cooler, Cooler Master Hyper EVO 212 as a minimum. As they said, you need to make sure your case isn't getting too hot. The general rules are more/larger intake fans than exhaust fans. You want some positive air pressure in the case for better cooling and less dust. Normally you have intakes on the front/bottom/side and exhausts on the rear and top.

That R9 290 will want a lot of air flow. Hopefully you can put a side fan on the case that will blow right on it.

GPU's will add heat to the case, even lower end models. I've noticed slighter higher temps in my XPS 8700 (MB & CPU), after adding a MSI R7770 PMD1GD5 (1GB GDDR5) OC'd out of the box. About 8-10C on both. Though the GPU itself is fairly cool, however I didn't game, I upgraded more for graphics appearance, which is why I went budget. The WEI increase to a 7.5 on graphics (both scores) was a positive side effect, it was 6.7.

No need for me to have a R9 290 for web browsing & running VM's.

I recommend babernet_1's advise here & will likely add another exhaust fan myself (honestly I don't think that one is installed). I did obtain some Arctic MX-4 thermal paste for the CPU (see specs in my sig) from Newegg on promo, but haven't got around to applying it yet. However, my CPU is far under the safe range, if I thought it were in danger of melting, or even in the yellow zone, I'd have already cleaned the heatsink/CPU surface & re-pasted.

Don't skimp on the thermal paste. A quality brand is needed for good CPU cooling. 100C is way too hot, it would be a shame for such a chip to go this soon.

Thanks for all of the responses! And im currently using a HAF XM cooler master case, its massive and i deliberatly bought it for the airflow. I have one 200mm intake fan on the front, one 200mm intake on the top, next to another 200 mm exhaust fan. Two 140mm intake fans on the side facing directly onto my gpu, and one 140mm exhaust fan on the rear. The psu is also using the bottom to intake air to cool itself. So altogether thats 6 fans and it still seems too ridiculous?

No you shouldn't have any problems with that case.

Your "top" fan should definitely be an exhaust though, not an intake. Have a look at the picture on Coolermaster website: http://www.coolermaster.com/case/mid-tower/haf-xm/ Both Top and rear are exhaust which is standard practice (cool air in the front bottom, warm air out the rear/top.

I don't know that that would account for blazing CPU temps, but I'd suggest you fix it and see if it makes a difference.

You haven't actually done any overclocking yet have you? Sorry if you already said that above and I missed it. You should never, ever overclock on the stock cooler or you will be able to cook eggs on your CPU. Just checking...

I took the side of my case off like you said and it hit the same temperature of 100c :( It's quite unusual when i quit the game, the temperature drops instantly back to an idle of 37c (ish)

Yeah i shall change the fan when i get in again, but i agree that it shouldn't make that much of a difference in the temps of my cpu even with the side panel open. And as for overclocking i havent touched anything in the bios apart from booting from my harddrive. I only have an approximate knowledge of computers but i don't suppose it could be my psu overpowering the hardware when it doesnt need to be? Its a corsair 600cx, it might be a stupid question but I'm taking everything into consideration haha

First step is to make that second top fan an exhaust. Then look at the CPU fan. Is it seated correctly? Did you apply the right amount of thermal paste? (about a pea sized amount). And again, if you do want to overclock, you need to install a much better cooler.

Being that you have a case with generous room, my suggestion would be in addition to installing the right amount of thermal paste (less is more), add a decent CPU cooler. Even if you don't overclock the rig. That's just too costly of a CPU not to spend $25-$40 for a good one. The Intel provided ones, they're OK for general desktop use (no gaming), but normally non-gamers doesn't buy the i7-4770K, the consumer/business model is the i7-4770 (like mine).

This should net an immediate temp reduction, provided that you also reverse that top fan to exhaust. I see that you already have the rear set to exhaust, that's OK.

Proper CPU cooling will also prolong the MB's lifespan.
