Motherboard temperature?

[ickymay]

theres nothing wrong with those temperatures on the CPU.

Where you testing and asking because you where getting crashes or just because Speccy said your temps where high ?

do you have any reason to believe your system is faulty ?

..... motherboard gets really hot (around 80'C) while the game is on, but when idle it is about 40-45'C...

Is that too hot??

I just want to remind people that the OP actually stated it was the motherboard temp he was concerned about not the CPU. I suggest you double check and clear that up as well. Maybe the mobo is overheating.

My system usally crashes when the mobo hits 45C - 50C even though my CPU is fine. During gaming I have to crank the case fans up.

When playing games like FarCry3, Hitman, Borderlands 2 (though they are NOT set high details and textures and so on..) after 10mins games either crash to desktop or everything freezes and a strange buzzing sound starts and I need to manually restart the PC.. I am aware that my PC is low-end but it should be more than capable to play those games ok on normal settings. When just working on PC everything seems to be ok.. If it was only one game that is crashing I wouldn't be alarmed, but seems whenever it is on heavy load it crashes.

Couple of weeks ago I took my PC to the shop because of BSOD prob and they changed that component that regulates power and voltages (sorry, don't know the English word for it) so that can't be a problem. That problem is gone now, but now this is happening..

I don't know how helpful this will be, but let's try HWMonitor (it's free):

http://www.cpuid.com/softwares/hwmonitor.html

It shows temps (along with other things), and maybe one of us can figure out what temps are for what. So what you'll do is leave this open while trying to play games. Then, we can compare its temps to what Speccy says.

What you're describing sounds to me like something somewhere in your system is overheating. I mean, you said they replaced the power supply, so like you said: that can't be the problem, unless the power supply they replaced it with is just as bad as the other one.

Is that motherboard or a processor temp? (don't laugh if it is the same thing)

Processor. And the temperature is ok, as told by that program.

Hmmm, the test is basically "do this complex math" and since it is repeated a few times the results in the panel (those strings of numbers) should be the same. You notice that the last one is different in either the first pass and the second time you ran it?

This means there is something screwing with the data elaboration even without overheating the CPU.

I'd have a look at RAM, and hope that is the cuprit, otherwise it's a faulty CPU.
Follow this tutorial.

But the CPU's core temperatures are very safe, nowhere near being too high.

 

[Duzzy]

RAM is definitely a possibility.
Hardware Monitor is good for showing min & max for a range of sensors including fan speeds.

With Hardware Monitor I would open it then let the computer idle for 5 mins then run a game but not too long, you don't want it freeze cause if you have to hard reset you'll lose Hardware Monitors readings. Try to play for a minimum of 20mins to 30mins or if that length of time is not possible just play for what you think will be safe.

Thanks guys for showing interest in my problem!
I ran memtest+ about month ago during whole night (because I thought RAM was causing BSODs, but it was power supply, it is now changed for a new one) and there were no errors, but I'll run it again tonight..

This morning I ran intel burn test again first thing when I turned PC on and it worked OK (10 passes), no errors and I was recording temperatures with HWmonitor (I'll upload the pic), but after that I tried the same test a couple of times and it always crashed on second or third pass, and temps look the same as the time it passed the test...

This is what HW temps look like when test fails

temperatures look great albeit with your fan running at 100%

what stands out for me is the low voltage on the 12v rail , with a quality PSU that should sit solidly around 12v with a maybe 1v allowable either side.

a poor PSU will allow voltages under load to drop and any of your devices like CPU and Ram will begin to generate errors due to lack of voltage.

I would keep that screenshot and ask them for another decent power supply not just another swop out cheap and cheerful ?

If you get the opportunity maybe ask them what make and model PSU they have fitted.

Thanks for the info mate!
I can hear my fan running all the time at 100% even if pc is idle, and it is kinda annoying.. Is there a way to set it to lower speed, or to set it so it could adjust itself automatically when higher RPM speed is needed? If there is a way to do so, please explain it to me, I've tried Speedfan but I guess I'm too stupid to configure it properly

If the +12V were that low, then his system wouldn't even function. It probably wouldn't even turn on.

These voltages are best measured with a physical meter connected directly to the cables instead of using software. Software is notorious for being inaccurate when it comes to PSU voltages.

 

[ickymay]

I agree voltage monitors are notoriously inaccurate but they can be indicative and I have seen systems run with voltages dropping under stress to below 9v ish when PSU's are faulty.

measuring with a meter is the shops problem I reckon and he cant break the warranty by opening the box

re the fan you need to know if its a speed controlled version and then set it in the BIOS, at this stage that might be something else to ask the supplier about ..........

Before I upgraded to Sandy Bridge, I had an E8400 in the Gigabyte EP45-UD3P. HWMonitor showed about 8V for my +12V, yet my system was working perfectly for everything I do with it. I had the same PSU that I have now (the original HX650). With my new parts for Sandy Bridge, I don't have a +12V measurement in HWMonitor. Everest is showing me 0.061V, and HWiNFO is showing 12.00V. ASUS AI Suite II is showing 12.00V too.

So, I guess I would recommend giving HWiNFO a try (it's free):

software so agreed inaccurate but as i stated before indicative and it did highlight a PSU fault.

to truly measure PSU output I do have a socket that links on to a motherboard plug but 9/10 I have found software for most probes that give an accurate enough reading by comparing outputs in windows to outputs in BIOS.

To the OP what are the voltage readings in BIOS ?

Maybe, but I had an ~8V reading for my +12V back when I had an E8400 in the Gigabyte EP45-UD3P. I had the same PSU then as I do now. The reason for the +12V reading back then was due to the BIOS reading I was getting. My current motherboard shows +12.00 in the BIOS, and so does HWiNFO and even ASUS AI Suite II, but I have no +12V reading at all in HWMonitor.

So I'm just saying, it could also be nothing.

Voltages readings in BIOS are ok, so for that +12 is around 11.5.. I think I have figured out what was the problem! My fans were stuck to 100% all the time, even when idle, so I have changed that in BIOS so now they run at 40%, but when game is on fans get up to 80% and temps are still fine according to HWmonitor! That stress test still says that PC running unstable, but all games and programs are running fine and without crashes so far!
Could have that 100% fan speed (and thus consuming unnecessary power) been the problem all along?

Does HWMonitor say 11.5V? Or does it still say about 8V?

 

[Solarstarshines]

Don't worry about that mine reads something like 11.71 I think it has a misreading when it come to accurate voltages

me and a few others came to that conclusion but temps are dead on
