New guy very concerned and confused about temps(AMD FX 6300)

A Jimbo Slice · Apr 17, 2015

Let me begin by saying I'm a novice, I built my own computer, and with the release of GTA V and finding out my cpu is my bottleneck, I wanted to try my hand at overclocking.

Youtube and google gave me the the direction and I followed, but my temperatures on the cpu were getting pretty insane. Which leads me to my first question of which CPU temp, should I go by in HW monitor? Package or CPU under the temperatures drop down?http://i.imgur.com/FuzyhgI.png

I tried just going stock 1.25 voltage with a 100MHZ increase, and my temperature rose to 69 Celsius in under 1.5 minutes, and it normally doesn't go above 54 so for such a small increase it seems like a big jump, yesterday I hammered down and went from stock 3.5GHZ to 4.3 at 1.4V(and several other tweaks that I followed in a youtube video, can link if requested, don't know specifics off hand) and I wasn't paying attention(please don't yell at me) while playing gta 5 and my computer shut down, so I restarted it downloaded prime 95, monitored the temps, and the package rose to 85 Celsius very quickly, like under a minute I'm crapping my pants quickly, tried a few different clocks/voltage combos and the same result, me having a heart attack that my computer is going to combust. I'm most likely doing something wrong, maybe my cooler is just shitty, maybe I need to reapply my thermal paste, but what I'm wondering is if this is a temp sensor giving me false readings and the computer crashed simply because it was unstable and not from heat, or should I just throw the towel in and not destroy my computer?(But that boost while playing gta 5 felt really really good)

Computer Specifications:
ASUS Crosshair Formula-Z
AMD FX-6300
MSI GTX 970
Shitty western digital hdd i forgot the name of
EVGA 650G PSU
2 x G.SKILL Ripjaws X Series 4GB 240-Pin DDR3 SDRAM DDR3 1866
Phanteks PH-TC12DX_RD Dual 120mm PWM CPU Cooler(Used thermal paste that came with this, I have arctic silver if thats worth a shot)

I'm just trying for the first time at this so please don't yell, yes I know I need to do more homework before trying again, but any suggestions appreciated, please let me reiterate to please not yell at me

I'm a bit confused with your temps too. I don't know much about your cooler but just looking at it appears better than the stock one yet the temps are higher than if you were using that. Are you sure the fans are spinning or at a high enough RPM if you're controlling them? What about case fans/air flow? How much thermal paste did you use? You really don't want the temps going over 62 on the CPU for prolonged periods.

Check the fans and try re-seating the heatsink for start, clean off old thermal paste on both cpu and cooler, apply a small pea size blob of thermal paste.

A Jimbo Slice · Apr 17, 2015

Max RPM for the cooler fans are 1800, and at those temps I saw them go to 1700, I can't use speedfan, I get a BSOD for some reason. I have 4 case fans, one on top of the case blowing into the case, which goes directly into the 'intake' fan for the cpu cooler, and the exhaust fan for the cpu cooler shoots straight into the case exhaust fan. I have a window on my case, and in just about the center is a case fan blowing directly on the graphics card, and I have another intake fan at the front of the case blowing just below the hdd. I want to say the case fans run at a steady 1200 rpm but 2 of them I don't have readings for for some reason, I think because of the connector used. I used about a pea size amount of paste, what I'm thinking is, when I mounted the cooler, it was a bitch to lock in, so I took it off and on a few times to get it right, so maybe that ruined that application of thermal paste, I mean, I expected lower temperatures with this big ass heat sink but its about the same as stock, when I have time this weekend I'll try redoing the thermal paste

Soulage · Apr 17, 2015

Your case cooling seems alright although I'd probably switch the top to an exhaust and flip the CPU fans around, following the natural hot air rises principal otherwise your trying to push hot air down. I'd definately try re-seating the cooler/heatsink though if you took it off a few times, air bubbles would have most likely formed.

Wait read it wrong the CPU cooler fans are probably fine just the top fan, something like this; http://media.bestofmicro.com/Y/T/312293/original/psu-bottom-04-EN.png

A Jimbo Slice · Apr 18, 2015

If I flip the cpu fans, then the intake would be right next to the case exhaust which is at the top back of the case, thats about 3-4 inches it looks like, will that be a problem? Maybe I outta get another fan for the top, I got a spot for 1 more, have the 2 tops exhaust, and the very back an intake blowing into the cpu cooler which then blows frontward which would be the flip you're suggesting, get what I'm saying?

Yeah, thats a better thing to do in that picture, the way I have it is the top fan before the cooler intake blowing air into the case, which probably just circulates hot air

Soulage · Apr 18, 2015

For now if you haven't already btw I'd set optimised defaults in the bios untill you can re-seat, just to reduce any heat/stress on the system as much as possible. Then try the OC again in small steps from stock voltage. Assuming the temps are under control after obviously.

A Jimbo Slice · Apr 19, 2015

I tried reapplying the thermal paste, but my temperatures are still insane, it rises so quick on an overclock. with 4.3 ghz at 1.3V it rises 1 celsius almost per second if not faster, while 2 cores are turned off making it 4/6 cores, i let it go to 65 before i stop the test. With default settings, my temperatures are about the same, although with a normal clock/ volatage its highest temp is 48 for package, before it was 55. Is there a cure time for the thermal paste, should I reapply it?

Soulage · Apr 19, 2015

Lemme try and get a bit more of an understanding whats happening where.
Idle temp:
GTA V temp:
Stress test temp:
Which stress test are you running too? Small, Large, Blend
Yeh some paste does have a cure time, depends which you used. Though it wouldn't be a drastic difference.

madmatt30 · Apr 19, 2015

Ill say this a million times , for fx cpu temps use the thermal margin in amd overdrive - nothing else is anywhere near as accurate ,hw monitor is absolutely useless,
r
that cooler is about on par with a 212 evo ,meaing you should have 30c or so clear headroom in overdrive when under load.

A Jimbo Slice · Apr 19, 2015

Stock and OC idle temp:15-25°C(It goes up and down constantly)
GTA 5 temp(STOCK): 45°
Stress test(STOCK): 49°
Stress test(OC): unless I stop it, it just keeps climbing, I let it go to 80 before I ended the test
I didn't a gta 5 test with an overclock because I don't want to crash again.

I did blend and custom, both the same temp result, the only thing I changed in custom is memory to use which i put at 6900MB, I used arctic silver 5, and I have been monitoring temps with HWiNFO64, coretemp, and HWmonitor and I can hear the fans spinning very loudly with the increase in temp

EDIT: Ran a blend at 4.3GHZ and 1.35V and watch thermal margin in overdrive, it went down to 10°C before I stopped the test, It took about 30-40 seconds to reach that from 55°C thermal margin

A Jimbo Slice · Apr 19, 2015

Something I thought of, the cooler comes with a 2-1 adapter to connect the fans, the box says max rpm is 1800, but im not sure for 1 or both, so since both fans connect to the 1 adapter into the same cpu fan spot on the mobo, could that cause low fan speeds for cooling even though they were getting loud? I was showing 1800 rpm in hwinfo so since its 1 plug for 2 that would be 900 each

Soulage · Apr 19, 2015

@ madmatt; Just downloaded AMD Overdrive Utility. So am I going by the TJMax as the limit? Which is being reported as 80 for the FX 6300 in Core Temp, the thermal margin is telling me 51, subtract that from 80 and 29 is my actual temp? But I'm also seeing the limit as 70 while googling. If it's 80 I'm 10 degrees out but if it's 70 the temp matches with what Core Temp is saying.

The splitter should be fine.
Those temps look alright at stock. What are all the settings you've changed when OC?
AS5 does have a cure time btw but I can't remember how long.

Just seen your edit, I don't think you'll be needing 1.35 to get to 4.3, I'm at 4.2 on stock volts. The extra voltage would cause extra heat.
Re-read your original post too, apologies I was tired when I 1st replied, you certainly shouldn't need 1.4 and thats where the OC heat is coming from.
But 1.25 and 100Mhz 69C didn't make sense and it looks like re-seating worked.

A Jimbo Slice · Apr 19, 2015

I'll will try 4.3 at stock voltage and see how it turns out right now, but I did try 4.0 at stock and the temps spiked, just not as fast but wouldnt stop

Edit: Just tried 4.3 at 1.25V and temps rose and there was 5 celsius left in the thermal margin, which i think is around 65. I didnt change any settings besides the core voltage and multiplier, cool and quiet is disabled, hwmonitor says the max reached was 161 c. which i think is a false reading, socket only got to 57. riding around in gta 5 highest temp was 34, socket 54, but typing is lagging a little while the game is open which doesnt usually happen, could that be an 'unstable' overclock?

Soulage · Apr 19, 2015

Remember though every chip is different, just posted mine as an example. You may need a little more V at 4.3 to be stable but then again you may not. It could be the same if I posted my settings for 4.2, you copied them and weren't stable but then again it could also work.
That's why you go in small steps raising multi, running tests then V as needed untill your goal is reached or temps/un safe V don't allow any more.

But was that before you re-seated the heatsink or after?

Don't load up the game straight away, run stress tests, the time between editing your post isnt enough. Run Prime95 blend for at least 20 mins to an hour if your temps allow.

A Jimbo Slice · Apr 19, 2015

Soulage :

It was after the reseat, but I edited the last part of my last response if you wouldnt mind looking, why are temps so high with prime95 vs just gaming, because this seems decent right now besides the lagging text, could that mean i need to up the voltage a tad? This is turning into a walkthrough, sorry man

Soulage · Apr 19, 2015

Temps are different under game load and Prime95 because Prime is designed to stress your CPU past normal load for stability tests.
More work/load, more heat.

A Jimbo Slice · Apr 19, 2015

Soulage :

Thats what I kinda figured, so to be on the safe side, if prime95 causes my temperature to rise to an unsafe level, I should fix/undo that overclock even though it may be fine while gaming or something else. I just want to be as safe as possible

Soulage · Apr 19, 2015

Well while gaming your temps wouldn't go as high as Prime95 so you have some margin but you need to run Prime to make sure the overclock is stable and isn't going to do anything nasty like cause BSOD or lock up your system. If your temps are exceding the safe limit of your chip for prolonged periods it can also damage or at least shorten the life span of it. You've got to find the balance.

It seems as though you might be at the upper limit of your coolings ability for Prime but I still don't know if that cooler should be performing better, did you reorient the top fan?

A Jimbo Slice · Apr 19, 2015

Soulage :

I appreciate the help, I'm gonna try a 3rd reapplication of thermal paste, because i did lift up the cool just a smidge after placing it down to get it placed correctly on the offchance that i fucked it up again, but the temps seems good for idle both stock and oc, and stock load temp seems good, but that huge spike with an overclock is what gets me, even at stock voltage, and upping to 4.0ghz its still too high, maybe my chip just doesnt like to be overclocked

I cant fit the fan right above the back exhaust, but I did flip it so its now an exhaust at the top, I read somewhere someone was achieving decent temperatures with the same cooler on an overclock, but maybe it does have its limits

I want to go liquid again, but my last computer caught fire because the liquid(oil) cooler leaked onto the mobo and graphics card and caused it to set fire, so I'm a little paranoid now
