No clue what to do, finally got temps stable on idle after having lot of trouble with thermal paste and re-seating the the fan.

On idle i get about 30-35C im ok with, but when i start gaming and i finish gaming temps will run about 60-65C and when im done im assuming temps should go down over time, but as it stands after i finish gaming my temps will only go down to about 55-58C range and sits like that.
I have to turn off the pc for an hour and comeback and temp will be back down to 30C range....but while its on its not cooling. Using a Hyper 212 evo at 50C it runs at 1800 rpm,

my specs are : AMD fx 8320 at stock clocks.
Hyper 212 evo fan
Gigabyte GA 970 D3 motherboard (with the F11 update)
HD 7870 GHz
800W psu.
Ive watched dozens of videos on proper thermal paste methods......and im done.....im clueless on what to do anymore, and i feel bad for having to keep coming back asking for help on something that shouldnt even be that complicated. But for those that do help i appreciate all you do.

Well, maybe to verify it isn't an incorrectly mounted cooler that is causing the issue, you could replace it with the stock cooler for awhile and see if the temps return to normal idle quickly as they should while running your games. If you have the same problem with the stock cooler, we'll have to look elsewhere. But if temps fall normally, then it would have to be EVO related.

It sounds like there's a possibility that your EVO's cooler isn't making good contact with the processor's heat shield. It can be tricky to get it installed properly if you've never done one before. I've had mine on and off of the one in my sig quite a few times. Also have an EVO on another rig I have. Are you screwing the 4 spring loaded fastening screws down all the way? Do you have the center pressure pin in position as it should be? How about the scissor bracket. Is it open correctly and not upside down?

the 4 springs are screwed in, the center pressure pin is in place the scissor bracket is in the correct position, and is not upside down, i want to switch to a different cooler down the line, but im not sure what to do, the temps do eventually go down, but they stay high for quite a while even at idle.

That sounds like an issue with ventilation. To test it out, open your case and blow a large fan into it. If the temps go down faster, it's a ventilation issue. Most people get a really expensive CPU cooler but completely ignore case ventilation, and this causes it to circulate the same hot air.

This is actually not uncommon the fx 8320 is basicly similar in heat issues with my 8120 i had the exact same issues and its actually the stock crap they provide you with

grab some mx4 paste
cotton swabs
Isopropyl Alcohol 99.9%
gift card hard plastic ( no credit cards etc)
new fan for rear of case use the stock evo for near the laptops
small foam square
coffee filter
http://www.newegg.com/Product/Product.aspx?Item=N82E16835129055

remove your cooler and cpu from the board be very careful of contact pins

gently put the cpu on foam and disposable cup put the isopropyl alcohol in cup and leave several swabs to soak

then gently apply enough pressure to remove the gunk of the old paste till the whole metal shield is free of paste or residue

dry of the cpu with coffee filter allow a 10 min waiting time to ensure its dry as the left over with evaporate and then sit and lock cpu back into its socket ready for thermal

now clean of the contacts on your cpu cooler clean the heatpipes well get in the grooves between the heatpipes as left over paste gets trapped there once you have all the thermal paste let it dry out make sure theres no thermal on the cooler at all.

next add a very small ammount of paste on corner of card edge and run it down were the 4 heatpipes meet each other to trap fresh thermal between there eliminating gaps.

next apply a small mx4 paste pea size amount i find 2 small ones are necessary for fx cpu chips

spread evenly with the gift card used for cooler press down a bit not to hard then drag the card round the cpu to spread the paste evenly till you can see no metal at all.

next take cooler and take your time and slowly lower it on to the cpu get the alignment dead on first time do not move cpu cooler around and then lock it down. tighten in x pattern e.g 1 and 4 tighten a bit and then 2 and 3 a lil at a time repeat until it sits tight.

now take a couple of cotton swabs go around your fx cpu were the cooler meets the cpu and go around it several times as thermal paste will have been pushed out add a very minuscule bit of pressure as you go around with a cotton swab so as you go around it picks up the left over paste and locks and makes a airtight seal.

finally gently put the evo fan on s by the ram or by the vga side if cooler faces up towards the roof
and plug that one up
and then attach with clips that came with evo to the aercool fan put this to rear of case or towards the top vent depending on which way you have the cooler facing.

plug up fans

and take her for a spin

temps your idle temp should be 30-33c
gaming temps should jump max 40-45c max when playing heavy games bf4 50c

You don't need to spread the paste manually. http://www.youtube.com/watch?v=-hNgFNH7zhQ

Also I don't know how you can tell someone what their temps should be since there are so many variables.

And you don't even necessarily need to remove the CPU from the board for cleaning.

ive done this method quite a few times with success and the other methods dont really work and as for air bubbles ive yet to get them as i never remove the card as im doing this

as for the temps ive owned both the cooler and used mx4 paste on fx 8120 and a friends fx 6300 etc the temps were within what i have stated when i did this hence why i put a line between the numbers to indicate the diffrent temps ive gotten doing this method

removing the cpu is much better as you can get the gunk of the cpu without getting in the way of other parts of the motherboard and sometimes the case can make angling when cleaning difficult.

The other methods do work, tried and tested. You're lucky you haven't gotten any air bubbles.

I own the cooler, mx4 and an FX 8320. Each case has different airflow, different number of case fans, different amounts of dust, placed in a different part of a room, differing sizes of rooms, different room temperatures, different climates... See where I'm going with this?

You should only have thermal paste on the top of the CPU so removing it is not necessary. You risk bending pins etc. in the process as you're applying pressure to remove the old paste if you've removed it from the motherboard. I don't know what kind of case would cause "angling" problems, maybe if it was mini-ITX, but even then you could remove the motherboard from the case, not the CPU from the motherboard.

"Don't really work" "i" "i" "i". You are making a lot of assumptions based on your experience only, and then you are telling him exact temps in a different case in a different house with different ventilation with DIFFERENT PROCESSORS. What he is getting is not due to not doing it exactly your way. I'm not saying it is necessarily ventilation, but I'm not saying that it IS the ventilation no matter what and if he just does what I tell him to do, it will fix it. It's called troubleshooting. Try it. I don't mean to be rude, but you're not being helpful by telling somebody everything they know is wrong and to not listen to other people, and while you do not seem to be acting maliciously or rudely, you are not helping.

Things that affect temperatures:
Case
Ventilation
Case fans
Ambient room temperature
Processor
Motherboard

You listed very specific temperatures, 3 and 5 degree differences. So unless you can guarantee you have all of the variables exactly the same, you cannot tell him exactly what he is going to achieve, nor tell him what his problem is. You tend to lose credibility when you fail to accept other options and proceed to tell people they're doing something wrong and that your way is the only way.
