hey guys I just finished building my new machine and I have a few issues I would like some input on. First off here is my new build.

intel i7 4790k 4ghz
ASUS HERO II Z97 motherboard
MSi GTX 970 4G gpu
Corsair 750w PSU
samsung 240gb SSD
WD black 2tb HDD
inwin GRone case with 2 additional fans
coolermaster hyper 212evo heatsink

so when I originally put the build together I used the stock intel heatsink with artic silver thermal paste. under 100% load using the intel CPU diagnostics program I had to shut off the test after about 30 sec. due to the cpu reaching 90C. also during gaming it was reaching 80c. I installed the new heatsink and re applied the thermal compound. now it did drop temps pretty well but for an aftermarket cooler Im not sure if its cooling very well. now under the same intel test I can run the whole 5 min test and the hottest it gets is about 75C, it idles around 30-35C. I am not overclocking yet but this makes me feel like overclocking will not be possible with this setup. is this about avarage for the 4790k? I know its a hot running CPU but I feel like it should be cooler than whet im seeing. Thanks.

80 and 90C isnt a problem. The CPU starts to throttle at 100C. You cant really damage it due to heat.

Also I am pretty sure you motherboard already autooverclock turbomodes. Try disable Multicore Enchancement or what its called in BIOS and test again.

My main pc is on a small tv stand with the front fan less then a foot from a 5500 btu ac to avoid cat hair and dust.
Yesterday DAI freezes up and wow I did not believe amount of warm air coming from the top radiater fans so I lowered the cpu speed and turbo voltage for the rest of this summer. This pc is also in a well vented half-x case which doesnt seem to help the cooling much.

I haven't worked with motherboards of different manufacture in a long time, although I still have a socket-775 Gigabyte in operation among the other household units. But ASUS has this feature under a BIOS "Tools" menu in which the user can store "profiles" -- each a different set of BIOS settings saved by the user.

That feature at minimum would allow you to address "seasonality" in the matter of ambient operational temperatures. I organize my profiles according to clockspeed, which still allows for the same easy choices.

ShintaiDK and I are always fencing with our comments on this topic, but there isn't much disagreement.

What I wouldn't know about the current-gen Haswell /Devils Canyon/ "Refresh" processors is how higher temperatures would affect overclock stability. Better stability is often cited for more effective cooling.

I could be wrong, but I think IDontCare had shown how a hotter chip will draw slightly more power at a given overclock speed and settings for a high temperature than for a lower one.

Depending on steps the OP has already taken for an airflow strategy in his computer case, I can say firsthand that ducting a 212 EVO to the case rear-exhaust fan may pay a dividend of as much as 5C degrees in better cooling. You can spend $5 to buy a TR blue-rubber accordion duct, which I can also say firsthand can reasonably fit a 212 EVO. Or you can build your own.

I did discover something useful the other day in this regard. I use Nestle-Carnation CoffeeMate as a non-dairy coffee-creamer, and it comes in a round, barrel-shaped 1kg plastic container. The container exactly fits the shroud of a 140mm fan, but "exactly" isn't a requirement here. You could cut a hole in such a container to match the shape and size of the EVO fins, widen the hole if needed to include a 120mm fan, and cut down the container to mate up with the case-rear exhaust fan. Since its plastic, you could paint it with plastic enamel.

I haven't had my coffee yet this morning, and these little solutions or possibilities are always in my mind -- either way I could seem a bit nuts for this suggestion of growing length. That's OK, though.:\

BY THE WAY. OP might correct the title of his thread. When I first saw it, I assumed he was talking about a Sandy Bridge E processor. So . . "3790K" should be changed to "4790K."
