CPU still overheating on new motherboard after applying thermal paste

Hello. Like the title says, before applying thermal paste it used to go up to 110+C degrees when playing GTA V ( that's how I tested the CPU temp ) Now, after applying thermal paste it goes at most up to 87C degrees and in idle 49-60C. What I should do now? replace the cooler ? replace the cooler and the heatsink ? Thank you.
 
Solution
well you know theres only two things you can do.

1. adjust cpu vcore manually.
2. get a better heatsink.


...looking at your bios i cannot actually see any option to adjust the vcore for the cpu (apu) ...unless you can find it.

thats pretty impressive result with the thermal paste and reseating. at least the cpu is now running within acceptable thermal limits...all you could do is get a better heatsink. noctua nhd15 or coolermaster hyper212evo perhaps..

what heatsink are you running right now?
 
"in idle 49-60C."

Either you have a very high ambient temperature, your cooler is not working as fast as needed, or your CPU is not working at stock values (it could be at stock frequency but with a higher voltage).

Let us know your full system specs to understand better what's going on.

AMD Athlon II X4 750K, 3400MHz, 4MB, Black Edition
Motherboad is new, just bought it 3 days ago, Asus A68MH-K

The cooler & heatsink are the stock coolers

The PC Is placed in another room, at MOST 30C Degrees at day if it's hot outiside. PC was just gathering dust for the past 7 months or so because the old motherboard died and I just replaced it. That could be the problem? because CPU wasn't used in so long?
 
Non use has little to do with it.
10-15c over ambient is what you should see at idle.

Two things to do if you want better temperatures.

1. Make certain your case is supplying sufficient fresh air to the cooler.

Two 120mm front intakes is good.
If you take the case covers off, does that help?
If so, look to better case cooling.

2. Stock coolers are not very good, particularly if you overclock.
Noisy too.
Downdraft coolers are not as effective as tower coolers.
Look for a $35 tower type cooler with a 120mm fan.

Case cover is off. I don't really want to put it back because I clean the pc occasionally, not overclocked, I mean, I didn't change anything in bios because I don't wanna change something I don't know what it does.

EDIT: This MB has APU, could that be the problem why CPU is overheating? Of course the integrated GPU is connected to the dvi cable to monitor, is there any way to "turn off" the apu?

try lowering the cpu core voltage to 1.35V this will lower your temps. thats assuming it boots and is stable at that voltage...

Boosted P states [1]
#1: 4000 MHz, 1.35V
#2: 3700 MHz, 1.325V

also check that your cpu clock speed is set to auto.
alternatively set clock speed to 3.7 test it. then set it to 4.0GHz and test that, at 1.35V and in small incremental increases if you have stability problems.

how do I lower to voltage, safely?

lowering voltage is not unsafe. the chip is designed to run precisely at the stock voltage.
if cpucore voltage is set to auto..it should run at that voltage. if it doesnt....it would be unusual, but only way to know is to enter the bios.

cpus can often run undervolted aswell at stock speeds.

It's on auto. And I can't seem to change it.

Something is weird, In bios when I go in it shows at most 40-41C degress. But when Pc boots and I check it on speccy,CPUID it shows 50-70C degrees.

when in bios your cpu is at absolute idle .. it will read more when in windows because there are processes running....even at 'idle'. the important thing is to ensure the core voltage is at stock voltage. in my opinion.

temperature is directly related to voltage. also the higher the voltage the temp increases exponentially it is not a linear correlation.

1.44V should not be required. no harm in trying. you certainly wont damage anything running a lower voltage.

page 40
cpu configuration, advanced, adjust the voltage...thats what i would do...whatever it takes to get your voltage to 1.35v on the cpu.

(you could run the cpu at 1.5V and overclock but you'd need a better cooler, but i dont think there is much overclocking potential in that chip)

i suppose there is the possibility of a faulty motherboard, but so long as your bios readings respond to your adjustments id say a faulty motherboard is unlikely...

well it looks ok to me. voltage wise.

quite frankly without mucking around in your actual bios and trialling various settings i cant think of anything else to do. the board as it is set is dynamically adjusting voltage as it alters frequencies up and down on the cpu which is ideally what you want it to do. by manually setting core voltage and core frequncy (by not using auto) this would give you more control. in my opinion. are you saying you cant change from auto to manual in the "advanced""cpu configuration" menu in the bios?

cpu load line calibration might help - set it to manual and try out the different llc options. sometimes this will actually raise the cpu voltage for added stability, but you wont know until you try the different settings. perhaps try disabling llc. this might lower the voltage aswell. but personally ive always selected the load line calibration manually. ie enabled and set to a specific level.... trial and error (and trial and success;) ) whatever gives stability at the lowest voltage.

disable load line calibration this will lower your cpu voltages give it a go.

hyper 212 evo cpu sink is a good price to performance. many people swear by it. if you want to significantly help your temps a good heatsink is the only way. the evo is quite cheap.

This is everything that shows up in cpu configuration

Also, this looks kinda weird.

btw, sorry for bad quality bios picture.

I can't seem to find how to adjust the vcore manually, anyways. Thank you very much for your time, at least I narrowed down the problem. Thank you!

this looks good though.
