Hi everyone,

So something that's always bugged me is how hot my system seems to run, today I done some testing and got the following results:

Desktop Idle:
Socket temp - 38-40 degrees C
Core temp - 19-21 degrees C

Prime95 test (10 mins):
Socket temp - 56 degrees C
Core temp - 43 degrees C

My setup is:
Asus Sabertooth 990FX R2 Mobo
AMD FX-8350 CPU (stock clock 4GHz turbo mode)
Sapphire R9 280X Toxic
16gb Kingston HyperX Beast 2400 MHz DD3 RAM
Samsung 840 Evo 240gb SSD
Corsair Carbide 500R case (stock fans given with case)
Corsair H105 CPU cooler (fans mounted in push config)
Arctic Silver 5 thermal paste

I'm looking at playing some more demanding games such as GTA V, Rainbow 6, and want to upgrade my GPU in the new year, but I feel like the system is running slightly on the hot side for stock clock speeds. I would like to overclock and have done before but always ended up resorting back to running the stock configuration as the fan speeds were getting ridiculous even just for web browsing.

I've done some research and found that the 8350 CPU starts throttling around 70 degrees (socket), and I'm not a million miles away from that even after only 10 mins of stress testing, I did actually end up with a blue screen after playing Fifa 16 for not much more than an an hour and 15 mins the other week.

One mistake I have made when building the system is that Corsair don't actually recommend the H105 AIO for the 500R case, although i've managed to get it to fit, could this be an issue to high temps?

Reviews online give praise to AIO coolers, but I seem to feel like I'm not getting anywhere with the Corsair, is it worth switching over to air? Or going for a more dedicated watercooling solution?
The pump does seem to be working, or at least I can feel vibrations when I put my hand on the pump, so I don't believe the H105 to be faulty.

Any help is much appreciated :)
 
what kind of fans do you have on it? the temps at 10mins of stress testing aren't awfully bad. idle seems a bit high, cool and quiet turned off? exhausting out the top of the case as well? might just be a case of needing better fans or more aggressive fan profile but unless you want to start overclocking or anything there's not really any need to change anything, it's cool enough and you probably wont be able to stress it to the point you did in the stress test with gaming anyway.
 
Thanks for the response.

The fans are Corsair 120 intake case fans (don't know model number), there's a 200mm side mounted fan which is used as an intake.
And also the two SP120L fans on top of the radiator pushing air into radiator and into the case.
With only one 120mm exhaust fan.

Cool & quiet is disabled.

I am tempted to get some Noctua 120's, or maybe even 140's and use them as two intake fans on the front of the case.

I have set up my own fan profile in AI suit with the radiator fans at 100% by 60 degrees to try and stop the temperatures creeping up.
 
Maybe try pushing the air through the radiator out of the case? Also you could get some noctuas, the Static pressure ones, and try it with them that may work better.
I am also having the same issues as you with my 8320 and H100... I honestly think its just the fans, but we will soon see :p Report back after you try some different fans in a different orientation!
 
I have a H100i on my 8350 and also have it exhausting air out the top of my case, I'd give it a go. I would really recommend changing the stock fans though just to save your ears.
 
Make sure the CPU didn't have to much thermal paste applied ( a grain of rice or a small pea sized blob is the most you need )

Those temps don't seem to unrealistic ?? And regarding the BSOD did you make note of the error #

Also what psu do you have ? The 8350s don't like bad power delivery and loads of motherboards cause them to throttle because they can't deliver the power well enough.
 
Using hwmonitor and during stress testing and idle what is the voltage that the cpu is using. The cpu's run excessive voltage from stock and I wouldn't be suprised to see a v-core of around 1.4-1.45v. When at 4.1ghz it should only need 1.25-1.3v so you could try undervolting using offset voltage. You really need the fx8 at around 4.8ghz to justify the expense of that cooler. Any reason why you have cool and quiet disabled? .

What's clear and is very common is that people replace the heatsink and fan with a aio cooler and then forget to provide decent airflow over the socket area.
That's why your core temps are so good yet the socket is high in comparison.
 
Those temperatures seem completely normal to me, remember that AMD CPU's do run quite hot - they are based on old process technology from 2012 etc. I wouldn't worry about those temperatures at all.

Check out this basic guide to case airflow, compare it to your build and if you have questions ask. ;)

Thanks for the responses, helped me a lot.

I'll try and answer and make some points as much as I can.

So last night I rotated the radiator fans, and they are now acting as an exhaust. I've not carried out any stress testing in this orientation, but idle temps are significantly lower, as much as 10 degrees! With 5-8 degrees being more typical.
Socket temp I'm seeing 29-32 degrees
Core temp I'm reading on HWmonitor as 17 degrees.

The system I built about a year ago now, a very small amount of thermal paste was used, but the H105 did already come with some applied which I removed and then applied Arctic Silver 5.
I didn't think to get the error# when I got the blue screen, didn't cross my mind at the time but would have helped for sure.

PSU wise I'm using a Evga NEX650G, 650w gold rated

Vcore voltage during stress testing was at a max of 1.392 V, Cool & Quiet was disabled when I overclocked before, I must not have enabled it back when I reverted back to stock clock speed.

I was mainly worried about the temps because I've read that the CPU will start throttle around the 70 degree mark, which I thought didn't really leave me much scope for an OC.

I've checked to get any part numbers off the front intake fans, but there doesn't seem to be any and nor are they PWM, since I've got the top HDD bay removed I may think about adding another fan in there.
It's a bit hard to try and plug some numbers in reference to the case air flow guide since I only know the airflow of the radiator fans :(
 
If you have access to a little remote thermometer like I use (actually I have 3 and usually use 2 when setting up airflow), use it. They really do help.
 
Well I've just carried out a little test, now running at 4.2GHz.

Before at 4.2GHz under load (Prime95):
Socket 55 degrees
Core 41 degrees

I had an old thermal take fan laying around, I think its a 50mm, operates at 2800rpm lol!
Anyway I put that in, positioned it where the top HDD bay used to be. I've managed to drop temps down to:
Socket 51 degrees
Core 37 degrees

Overall dropped 4 degrees across the CPU. I also noticed how big a restriction the top fan cover/grille is, as temps dropped a lot quicker with that removed.
The extra fan didn't do anything to Vcore temps though, they were still hitting 62 degrees, with the Vcore being the otherside of the CPU socket I don't think the old thermaltake fan had enough manpower to flow that far.

Anyway gives some food for thought, will be considering some other fans shortly and a temp probe to try optimise flow through the case as I'll be OC'ing further :)
 
Just be very careful.
Playing with airflow is extremely addictive.
It's already got you using old 50mm 2800rpm fans. ;)
 
I'd re-check temps and that there's no throttling, run amd overdrive stress test,
overdrive will show cpu frq for each core and temp margin to throttling.

Done this and showing between 29.9 degrees minimum and 32 degrees maximum of thermal margin, that's at 4.2GHz, 1.356V. :cool:
