hey guys i not long finished my new build and recently started playin the division im running cpu temps program and keeping an eye on my CPU heat and its getting from 50-70 degrees is this normally i have had rare moments it spikes to 80 - 90??
shall i change my thermal paste rather from the stock one i got from my hydro pump?
80-90 on a CPU is quite high.
Which CPU, and which cooler are you using?
Applying your own TIM is a good start. Is the radiator fan working? Is the radiator extremely hot? Does the pump feel like it's working? Do you hear air bubbles in the loop?
im using i7-4790k with corsair hydro H60
i can feel afeint vibration from the pump but thats about it, fan is working rad feels cool, aslo on idle sits around 30-35
30-35 is around normal for idle. You should be hitting around the 65-70 mark on a CPU stress test. 80-90 is in the danger zone for me, although I think Haswell's begin to Thermal Throttle at 102.
Getting into the low 90s for that CPU is actually 'normal'... they run very hot.
TL and I both have the 4770k, runs a few mhz slower than the 4790k. We have both de-lidded our CPUs to clean out the useless gunk intel use to transfer heat from the CPU die to the heatspreader, replacing it with better quality material. After that, and with a H100i, my CPU gets to around 75 as a maximum.
You can try things like changing the TIM, or simply increasing the fan speed on the H60, but the only thing that makes a considerable difference is a de-lid. Not something to be done lightly, though, as it is very easy to ruin an exposed CPU die. Damage one of the transistors under the heatspreader (they are miniscule) and you will kill the CPU. If you are happy with temps in the low 90s, and that is indeed as high as it goes, I would keep things as they are.
Edit - there is actually another option that can help quite a bit...
1) Make sure you have the most up to date BIOS for your motherboard.
2) Go into said BIOS, UNDERVOLT the CPU. Just find out the lowest voltage the CPU needs to run without issues. By default your motherboard will be giving it more voltage than it needs (which motherboards do to accommodate the variable quality of CPUs). You can easily shave off 5 degrees if your mobo is giving too much juice.
Yeh I have boosted my fan speed to turbo for all fan not just cpu I tend to find its major heats up when I load up or am loading a game my thermal paste comes Monday so I will try that then, if not I might get a bigger case and a h100i to accompany it I have a feeling h60 work a lot better for i5 and lower
Just don't be surprised if those things don't change the results you are getting.
The rubbish TIM between the die and the heatspreader is more likely the limiting factor than the H60.. and changing the paste will almost certainly change nothing significantly.

Undervolt in the bios... then repeat prime and see the difference...
Its hot but I am just worried for you that you will not see the change you are hoping for with a new cooler / simple paste change.
i tried to undervolte but keeps coming up blue screen
How much are you undervolting by and is it from standard clocks? If you udnervolt and overclock it's a bad combo. Either way, those temps are not ideal.

I have the same CPU and cooler, I get 56 degreeC under load with 2 monitors at 2650x1440 and a GTX 980 (ok not exactly responsible for the CPU but some games higher res strain the CPU). I would think that your ingress fan might not be getting clean cool air or your case isn't extracting air properly. That CPU should never run at that temp with that type of cooler I would say.

not by much only 0.010 at a time also its not been overclocked
I meant to point out that the temperature variance between cores is rather high, normally I've seen a few degrees difference, but 77 - 90 is quite a lot and does suggest the cooler isn't properly leveled or the paste has air bubbles in places.
I overclock and as I said 56 degrees max, same CPU, same cooler.

ok well i will have too wait till monday to swap paste i got artic silver 5 anygood even for de-lid use?
found out they way to undervolte! just me being a dope, I changed it from 1.712v to 1.690v already a big difference, been on stress for 15mins max 74 degrees but after half hour 3 cores went abouve 83degrees!! so shall i keep going or no its fine as it is?

Keep lowering the voltage until the CPU starts to complain (blue screens etc) and then bump it up by a couple of notches and run at least a 12 hour prime stress test. Then you have just about found the lower point of your vCore. There are other voltages you can lower too, but the vC is the main contributor to heat. As you can see it has already yielded results.
You can also try a reseat of the cooler if you want to, but like I said its 99% not the problem here.
@Albert - if you have that CPU running at those temps without a delid or undervolting, you have found yourself a CPU gem. The whole 47xx range are notorious for heating up into the 80s and 90s on stock speeds. There will always be odd CPUs that outperform their counterparts... I think you're morally obliged to overclock the thing ridiculously now :D
Edit - and no do NOT use arctic silver for a delid. If you are happy with the temps after some undervolting, don't do a delid. If you do want to, thoroughly read up on the subject before you do, like I said 1 wrong move and you will brick your CPU... nice new (very light) paperweight.
The other thing to remember is that too much AS5 (or any other thermal compound) can cause these type of high temps and variability (much as Albert suggested). The idea is to use a seriously small amount, if you put on as much as a pea then you put too much on. Use little and spread it out, a little goes a very long way. I use a credit card to spread mine and I reckon I use about a quarter of a pea to do my CPU.
Marrowfat or petis pois?
There's an opening in the market for someone to manufacture cooling paste ready spread on a patch.
Maged to got to 1.660 now gunna stick with it as all cool temps max was 70c
If you're getting max of 70s on a stress test, likely it will be in the 60s or even 50s when gaming - these are good results, means you actually have a pretty decent chip there (see what I said to Albert!).
It also pretty much confirms there is nothing wrong with the heater or the factory TIM... you can replace with your own AS5 or whatever if you want but I doubt you will see much of a difference.
I think a big issue with the 47xx chips is a combination of crap TIM between die and IHS, and that the overvolting by motherboards at stock causes ridiculous temperatures. If you can fix either one of these, you can sort out the temps. By undervolting you sort out 1 of the 2, and don't need to put your CPU near a vice and hammer. I did both, and then overclocked mine from 3.9 to 4.8... but that is only because I like the challenge of doing so.
So basically my thermal paste arrived to day I applied it and now My pc does not work everything has power but all I'm getting is a black screen,no bleeping nothing ,,(ties noose)
Ignore that the moment I pressed enter on my phone she woke up its all good
