So, I'm starting to get a little worried about my haswell temps. I'm running stock clocks on a Asrock z87 extreme 6 with stock cpu cooler. Phantom 410 with 4 fans, 2 in, 2 out and an MSI n760 graphics card. I don't think the issue is with my case because when gaming my n760 is maxes out at 67C but my CPU seems to max around 70-75 C. I haven't done anything intensive yet except browse the web/play games.

I have a ceiling fan, and the AC isn't always on here. The room is around 28 C (summer time in NJ).

At idle the lowest I've seen is around 33C and the highest Ive seen is somewhere around 75-78C. Should I be worried? Do I need an aftermarket cooler even though I am not overclocked? If so, which should I get?

Also, settings are on balanced, case fans are plugged into case fan controller (and set to highest setting). Airflow around the case is pretty good IMO.

You might want to read this article from here at Tom's, it's about cooling the Haswell CPU's.
http://www.tomshardware.com/reviews/best-heat-sink-haswell,3554.html

The recommended cooler is around $75.

Seems the Haswell CPU's run really hot because Intel decided to use thermal compound between the CPU die and Heatspreader. Other CPU's they used solder that conducts heat much better.

Good luck and post back what your results are for the people following this thread.

I'm not 100% sure what the MAX Temp of that CPU is, what I've found seems to indicate 72C. So if your really getting 75-78C I'm surprised your unit hasn't been automatically shutting itself off.

Anyway, when you assembled your system, are you sure thermal compound was installed on the Heat Sink or CPU heat spreader???

Also, what are you using to monitor your temps? You can use HWMONITOR by CPUid.

And use prime95 to stress test the system, see what max temp the CPU generates.

I've been monitoring it using HWMonitor and I haven't used any stress or benchmarking tests yet. Since I used the stock cooler I'm pretty sure the thermal paste comes applied. I didn't use my own or anything.

Just verify for me, you are looking at the temps in the CPU section and it does show temps for the 4 cores? Right? And you are looking at the Celsius temps and not the Fahrenheit temps?

If that is correct, is the cooler properly seated on the CPU?? Could be cocked and not making full contact.

You can also use CPUz to monitor the CPU speed as well, if your not already doing so. You could see if the CPU is throttling itself when the temp goes up that high.

Here are the temps after running prime95 for 2 minutes. Literally 2 minutes, this is not good. Also I'm fairly certain CPU fan and all are installed properly. I'm just going to buy an aftermarket cooler now I think. Any recommendations for $40-50 budget?

That's a little out of my budget. I'm going to have to read up and look for some alternatives. Also, it could be the summer weather here that's causing these temperatures.

Even adding a side fan might help out with the temperatures. I think I'm going to try that out first. Add in a side fan and see how that goes.

i have same CPU and that is normal
when u play games if the temp of cpu is in 70 that is ok dont panic
and dont worry about prime temps because in prime cpu takes up to 0.1v more so that's why u got that temps.
in games like u see its ok .
save ur money for later when u overclock but even then when u have 100 bucks(euro) cooling solution ur temps in prime WILL be 80 90+ depends on how much voltage u will need for stable overclock (if u delid ur chip it will be lower but thats OT atm)

bottom line check ur temps in programs u use everyday (games ...) and if ur temps are in 70 ur ok .

and dont run prime anymore

Thanks for the input. I never planned on stress testing the rig but got curious with the temps. I don't plan on running it again either. Usually when I'm doing real work it seems to float around 60-75. Idle seems to be around 30-35.

I'm probably going to buy an aftermarket cooler with the rebates I got from the rig so it's technically free. I'm eyeballing this Xigmatek Dark Knight II right now: http://www.newegg.com/Product/Product.aspx?Item=N82E16835233029

After studying and rereading that article I mentioned, it appears the Dark Knight cooler your looking at is basically the same cooler they tested, the Night Hawk series cooler that is in a white finish. Looking at the CPU temp over ambient chart (pg 22), that Night Hawk has the worst performance.

One that is only $30 is the Zalman cooler they tested. It was actually able to cool a few degrees better.
http://www.newegg.com/Product/Product.aspx?Item=N82E16835118099

I noticed it actually has 4 heat pipes instead of the Dark Knights 3. Looking at the article, the ones with MORE heat pipes seems to perform better. The $75 Noctua actually has 6 heatpipes.

If it were me, I would give the Zalman a try. But that's just the conclusion I've come to. Good luck.

reseat your cpu -- use some new paste.....google how to do it
