Need some help. . just baught a new Setup/Rig/etc

Okay Spec's
i7 4790k Devils Canyon
nVidia Geforce GTX 970 4GB
Z97 G-45 MOBO
8GB DDR 3 Corsair Vengance
250GB SSD
CORSAIR cw 650w ps
CORSAIR 650 D CASE
Enermax 120 watercooling for the cpu.

cpu idle 35, in game + tv playing movie 50-70 (this is my main concern)
GPU idle 29 in game 40-65
Mobo reading idle 32 and gaming 40-60

I am running a 32 inch TV + 20"Acer on CPU onboard, and a 24" samsung on the GPU.
Ive not touched anything, its all stock standard, i used to know more about computers then i do know, i remember as much not to screw around with settings like voltages etc etc im not sure what anythings running at, i used to have a older brother who would help me with this kind of stuff.. setting the speeds etc.

Any idea's on if these are okay temps or am i right in wanting to get the CPU temps down!?

for the CPU that range is safe under load, I would not be worried unless you constantly get over 80, so if you get max 70 maybe occasionally 75 you can relax that's not going to cause any problems.
Your GPU is running a low temp under load imo nothing to worry about there either.

Really they should be able to go up to 90 (though if it were going that high for long periods you could wear out the component), When it get to a point of too hot you will find your system will just suddenly power off to protect your CPU/GPU from damage, this would normally happen around 95 I believe from what I read.

Okay so i decided to wipe of thermal past put a neater thin layeer over idle temps are same etc etc, but i ran a stress test by Prime95 and the temp shot instantly to 70 and ive got my fans to auto to full power at 70c so at all my fans maxed out it instantly still continued to rise to about 84 after seconds id say 15-30 seconds of mostly me panicking and trying to figure out how to end the stress test.. (im pretty sure thats quite high am i right or? ive used the OC genie, so since my first post the CPU is now running (4.4 but in the stress test it maxed out at 4.2) i have no clue about voltages etc unfortunatly... Im kind of lost (infact i almost had a freaking fit when i tried to turn on my pc after re-applying thermal paste.. putting to much on... wiping it of, putting some more on and finaly getting a nice thin layer... putting it all back together and it wouldnt power up ( had this issue at start fiddled with tightness of the enermax watercooler and eventually after a blow on the ram it started.. again in games i havent seen temps rise past say 75 MAX but that stress test has got me a tad worried!!

Yeah Thermal paste can be tricky to get just the right amount on, not too much or little. I normally stick with the stock coolers so I don't have to fiddle with it (fan noise doesn't bother me). Having a look at how little thermal paste is on the stock coolers gives some idea of how little is needed.

Don't freak out about the pc not starting first go, this is not uncommon especially when doing coolers, adding or switching cards or ram in the system. I normally have to go reseat everything , ram, gpu's after fiddling with anything attached to the mobo. Normally because just the small amount of pressure exerted on the board when attaching the cooler, gpu or ram can make other components come slightly out of their sockets and then yeah the pc won't start or might even bluescreen on the first boot but then fine every boot after that.

This is behavior I expect from a pc after doing these kinds of things, it sounds like you got the grease amount just right (you should have seen the first job I did before I learnt!) and the temp while gaming is well accceptable/safe.

As for the Stress test, I think they are more stressful for the owners sometimes, remember these tests are different from your typical benchmark. They are designed to stress the equipment under higher loads then they would under normal even demanding applications, they are great for testing system stability to see if the system will crash or just power off if clocked too high.

Given your system appears stable I wouldn't change any voltages.

I had the same reaction as you did but with Furmarks stress test on my gpu's, it would go up to 90 and yes I was sitting there freaking out going how do I stop the test ARRRRRRRRGH!. But after running my setup over a year I never saw the GPU go higher then 75 except on the rare odd occasion. The stress test will make it go that high again still though, and I only run them when getting new hardware or a new config. I think running stress tests unnecessarily and regularly would actually shorten the life of the hardware in the long run, so only run when necessary (And that's why they usually have the warnings about the stress test having the potential to damage your hardware before you run then).

The same thresholds apply for both GPU and CPUS's, you don't want it running over 80 constantly, 75 is ok. System will shutdown or crash if it gets too hot 90+ to prevent damage to your cpu/gpu. So if you PC started to crash a lot or power off suddenly and kept doing it then that's when I would be worried and monitoring the temps again. 75 is not bad under normal load from gaming.

** Edit: While my core i5-3570k sits around 59 degrees under load I have also checked around and seen several reports from users with the exact same CPU as yours getting those temps, so while it is higher then some other models cpu, it is fairly normal for your particular model, and within the general guide lines for safe temps as mentioned above anyway.
