AMD FX 8350 overheating on BIOS

[theseminoob]

Hi, I've got this problem with my rig. I Assembled my First PC. I disassemble and re-assemble many PCs before but it's my first time buying/choosing the parts.

Here are the parts used for my rig:
- ASRock 970 Extreme4
- AMD FX 8350 (8 cores @ 4GHz) with stock cooler
- G.Skill Ripjaws - 8 GB : (2 x 4 GB) - DIMM 240 pins - DDR3
- 1 x SAPPHIRE 4GB Radeon R9 270X
- Gaming Power Netzteil 780W PSU (not yet delivered so for the test that got me my problem I used a 520W corsair PSU)
- Akasa Cavalry ATX PC case.
-2 HDD : 500GB + 1TB (none of them were connected since I needed enough power to turn on the PC).

THE PROBLEM:
when I boot my PC it automatically goes to the BIOS (maybe because no hdd is found or something else..). I can from the BIOS monitor the CPU temp, Motherboard temp, CPU fan rpm and if available Case fans rpm.

(Values may vary a bit from boot to boot!!!)

Outside of the PC case

what I get (first 20secs):
CPU temp @ to 40°C
Motherboard temp @ to 33°C
CPU fan speed @ 4100+ rpm (I don't recall).

After nearly 5min:
CPU temp @ 56°C
Mobo temp @ 45°C
CPU fan speed @ 4909+ rpm.

At that point the CPU fan makes a loud high pitched sound (as a turbojet engine before the plane take off or a vacuum cleaner sound if you will) which worries me (I think the fan's motor gonna burn out) so I shut the computer down.

Inside the PC case:

the first 20 secs
CPU temp @ 38°C
Mobo temp @ 30°C
CPU speed @ 4140 rpm

after 5min:
CPU temp @ 55.5°C
Mobo temp @ 37°C
CPU speed @ 5601 rpm

same scary sound -> I shut down!

(I didn't take PC case rpm since their sound level was close to that of fridge)

MY QUESTIONS:
-Should I change my cooling system?
-If I should, can I use a AM3+ compatible mini-ITX cooling system (i.e low profile) like EKL Alpenföhn Silvretta, Zalman CNPS2X or Thermalright AXP-100.
-Can I use a non-top-down blowing cooling system? (ASRock stresses me to use a top-down blowing system for FX- processors)
-Does the PSU power affect CPU temp?

BEFORE ANSWERING:
-I would like you to take in consideration that those are boot/BIOS temperatures no OS, Gaming or Average to High Computing temperatures
-I won't overclock

Thank you in advance!

yes you should most definitely swap your cpu cooler, the coolers that come with the cpu when you purchase them aren't that great at all, and have you thought of switching to a different thermal paste? Yes you can use any am3+ compatible cooler as long as it clears your ram and so on. Looking at your case it should support anywhere up to a 160mm tall heatsink, that being said I would recommend the Xigmatek Gaia for passive cooling, or if you have the room in your case and are willing to put a bit of extra money into a Cooler Master H100I would be the best option for your cpu. I hope I was able to shed some light on your subject.

Hi and thanks for the answer. here's a link for the case http://www.akasa.co.uk/update.php?tpl=product/product.detail.tpl&no=181&type=Chassis&type_sub=Mid%20ATX&model=A-ATX01

thanks again.

Xigmatek makes some good coolers, I personally use the Xigmatek Gaia and absolutely love it, but for an 8 core FX cpu I would recommend a closed loop water cooling system, looking at that case you should be able to fit a Corsair H80I

Right now that kind of cooling system is to expensive for me (every cooling system above $54 is). I guess I'll go for a twin heatsink cooling system and since closed loop water cooling looks like the best option, as soon as I can afford one I'll go for it.

well the Xigmatek Gaia is only at $34 atm, I personally use this heatsink and my cpu never goes above 38c (dual core AMD OC 3.4GHZ

H, thanks again for your reply. I'm gonna look into it and and maybe some reviews of other CPU Coolers 'til I find which one has the best cooling capablility/price value.

First of all, CPU temp shouldn't move pretty much at all while in BIOS. CPU is idle. You sure you did seat the cooler correctly? Its hell to push in the stock AMD cooler, took me almost an hour and considerable pressure, I thought my motherboard would break (why it took an hour, I was cautious).

Second, a watercooler is not required and I wouldn't recommend it either. A Noctua cools better and is more quiet. Check benchmarks if you don't believe me. Watercooler has fans too, you know. And Corsair etc have pisspoor pumps since its built into the CPU-heatsink. Water throughput is low, cools poorly. Another thing is the noise-problem they have had in the past. The pump makes an annoying sound. Only fix seems to be to RMA it or lower power to the pump (you fix it).

Pricey but worth it.

That Xigmatek, is it certified for 125 W CPUs like the FX-8350? I can't find that info anywhere. AMD dualcores are only 95W.

 

[Mack_Bell]

I do believe it is, I know and have known it to be used on 125w cpu's and never heard complaints. Infact I just saw on another forum someone using the Gaia with this exact CPU and they said theirs never goes above 40c under load.
