Hello. I am having a problem with my fairly new PC (~6 months old), and I was hoping to get some help.

First, here are my specs:

Windows 7 Ultimate x64
2x MSI GeForce GTX 470 Twin Frozr II Graphics Cards in SLI using 285.38 Beta drivers
Intel Core i5-2500K 3.30GHz (Sandybridge) Socket LGA1155 CPU
CoolIT Vantage A.L.C. CPU Water Cooler
Corsair Memory Vengeance 16GB (4x 4GB) DDR3 1600 MHz CAS 9 XMP
ASUS P8P67 EVO Intel P67 (Socket 1155) DDR3 PCI-Express Motherboard
Corsair HX Series 850W Modular ATX2.2 SLI/Crossfire Compliant Power Supply
OCZ 60GB Vertex 2E SSD (Boot)
1TB Samsung HD103SJ SpinPoint F3 SATA-II 3.5" Hard Drive (Storage)
Western Digital Caviar Black 1TB Hard Drive (Games/Applications)
Coolermaster CM 690 II Advanced Pure Black Gaming Midi Tower Case


For a while, I have been happy using the standard AISuite II that came with the motherboard, for keeping a check on my CPU temperatures. I have played many games, some quite graphically intensive, and the fan on my GPUs/CPU have not had to spin up. There was one game where it did spin up the GPU fans, but I cannot recall which game that was.

Anyway, I have been trying to play the new Battlefield 3 beta, and it is causing both my GPUs and CPU to heat up massively, to the point where the computer started beeping at me (which I can only assume is an overheat warning). This is after maybe 5-10 minutes of play.

I installed EVGA Precision to control the GPU fans, and Real Temp to check the CPU temperature.
At idle, the GPUs are at around 48°C, and the CPUs around 40°C. As soon as the BF3 beta starts up, the GPU temp is up to around 63°C, and the CPU is at about 60°C. this is after about 5 seconds of the game being on.

10 seconds in and the GPUs now read about 70°C

At around a minute, the GPUs and CPU both read around 75°C. The GPU fans have ramped up from 40% to 55%

At around 2 1/2 minutes, the CPU is up to 80°C and still climbing. The fan is running at 100%

It was at this point I checked the little LCD screen built into the CPU cooler, which read 55°C! I quit out of the BF3 beta, and instantly AISuite and Real Temp showed my CPU temperature to be the same as shown on the CPU cooler's screen.

About 5 seconds later, the GPU temps were down to around 58°C, and and fans had ramped back down to 40% (idle speed).

I know I dragged this out a bit (I was writing down all the temps as they happened), but I need help with this. If the LCD screen on the cooler is registering around 55°C under fairly intense load, why are Real Temp and AISuite showing it as being a lot higher, and why did my computer start to beep to tell me it was overheating?


Please help! There are a lot of graphically-intensive games coming out towards the end of the year (BF3, MW3, Skyrim etc.), and I don't want to live in fear of them!


PS: Please forgive me if this is in the wrong place, but it deals with multiple components and I didn't know the best subforum to place it.

Real Temp and AISuite pull temps assuming they know the temp probe. they don't always get it right. You MB has temp control "ASUS Quiet Thermal Solution :
- Stylish Fanless Design Heat-sink solution & MOS Heatsink
- ASUS Fan Xpert "
that may be confusing realtemp. (I love realtemp, nice program).

So do you think I should remove AISuite (which includes Fan Xpert)?

I had the same thing, and the temp warning was totally unnecessary. You dont need to remove AISuite you just need to disable one of the temperature monitoring features within it.

Realtemp and HWMonitor are both good programs that you can use to monitor your temperatures.

BF3 is a very intensive game, i was experiencing the same high temps which id never normally see unless running PRIME95 or KOMBUSTOR.

Ideally keep your GPU under 85 and keep your CPU under 70

I went into AISuite, and disabled the CPU Fan in Fan Xpert, and Also turned off the alerts in Probe II, but I still got the motherboard beeping at me after about 10 minutes of play.

I alt-tabbed out of BF3, and the temp was showing at around 80°C for CPU. Once again, the second I closed BF3, and temp dropped back to the mid-40s. Surely that is not enough time for the CPU to cool down?

Here's a picture of inside my computer. As you can see there are 2 fans on the side (1 in, 1 out), 120cm on the top, 120cm on the front, and one on the CPU water cooler. So cooling isn't an issue.

CPU and GPU can both cool very quickly. I think it only takes around 8-10 seconds or something like that to go from load temps back to near idle.

Yes, but this isn't 8-10 seconds, it's instant. I close BF3, and the temperature drops instantly.

Like I said in the original post, the second BF3 starts, the CPU temp jumps up. There is no gradual climb, the temp goes from ~45°C, straight to ~60°C
September 30, 2011 9:03:19 AM

First thing you could do is to use some compressed air to clean the comp.
If you are good at computers, id suggest changing the thermal paste on the gpus.
That last thing will especially help if you are still running on stock thermalpaste (in my case idle droped from 42 to 31 (a bit sick if u ask me), and load from 89 to 72.

This was on a 560Ti gigabyte version.

Sounds more like a bug/glitch somewhere to me then. An instant jump/fall is well, seemingly impossible unless your using a furnace or liquid nitrogen!

Yeah, it seems that way to me too.

There a little more backstory which may or may not help:

I had this problem before (AISuite showing instant jumps in temperature), and someone recommended Real Temp. I started using RT, and it was showing the real temperature (ie the same one as listed on the CPU cooler's LCD screen).

But recently my Caviar Black HD went bad, and I had to replace it. I decided to reinstall Windows at the same time, and start fresh. Except this time Real Temp is not showing the correct temperatures either.

Does anyone have an idea what might be causing this problem?
September 30, 2011 9:25:55 AM

GPU temps sound fine to me, but the CPU sounds like a problem.

I think there's a problem with the way the motherboard is reading the CPU temp or the CPU temp sensor is screwy. Is the BIOS up to date? Is the temperature of the CPU in the BIOS reasonable? Is there a thermal shutdown setting set in the BIOS which you can turn off?

If that doesn't solve the problem. I'd run Furmark and Prime95, separately and together to narrow down for sure if one of those are causing the problem or if you are developing a bad power source.

I just used the log in Real Temp. Here is what happens to my temp when I close BF3:

09/30/11 10:37:24 0.00 76 81 80 79 76 0.0
09/30/11 10:37:26 0.00 70 70 70 71 75 0.0

09/30/11 10:37:29 0.00 59 59 59 58 74 0.0

I have already run Prime95, but I have no idea what it did or why I did it, I just followed the step on Real Temp.

Because the temp drops so rapidly, I have no way of checking to see if the temp is reasonable in the BIOS. The BIOs version is 1502. There is a newer version of the BIOS (3 actually - 2 are beta though). I will update to the latest stable version and try that.

The temps cooling speed looks fine, its what you would expect from a good cooler.

They are high though. 80 degree's is really pushing CPU boundaries. Is your CPU over-clocked at all? What voltage are you running?
September 30, 2011 9:56:22 AM

Prime95 just runs your RAM and CPU without doing anything to the GPUs. If your computer shuts down after it running for an hour it's your CPU and you can not worry about what the vid cards are doing.

That's just the thing Stardude - my PC has never shut itself down because of overheating, and I have often left it on overnight to download a big file or something. The only time I have seen it overheat like this is when playing the BF3 beta.

Oh, I updated my BIOS, and left everything stock (all I did was change the boot device back to my SSD, and turn off the logo so it boots a little quicker).

I then started up BF3, let it load the map, then closed it. Here's the Real Temp log:

The temps in that last entry look ok. Those mid 60 temps are about ideal.

Your CPU cooler should be more than capable of keeping temps under 70. Just looking through this GURU review ( http://guru3d.com/article/coolit-alc-vantage-review/8 ) it shows even when pushing 1.5v though an i5 the temp at 100% load is 70 degrees.

Maybe its the CPU cooler at fault?

------

EDIT: Are those above temps AFTER updating the BIOS? If so then they look good and that seems to have sorted any issues.
September 30, 2011 10:11:30 AM

Whatever updating the BIOS did looks like it fixed the CPU temperatures. Agreed, 40's idle and 60's load sound like good typical values. Does it crash now?

Like I said it NEVER crashed. It started beeping so I shut down the game, then after a few seconds the beeping stopped.

It looks like the BIOS update hasn't done anything. I just tried playing BF3 again, and the temps were hitting high 70s within 5 minutes.

Here's another Real Temp log.

Maybe its the CPU cooler at fault?


I don't think so. As I said, the CPU cooler has a LCD screen on it, which shows the current temperature. Even when playing BF3, it isn't going over 60°C, usually hovering around 55°C

Is your CPU over-clocked? What voltage?

Im not sure which is more reliable, the temp monitor built into your cooler, or the hardware monitoring software on your PC....so i don't know which to "believe".

It was overclocked using the AISuite software, before I flashed the BIOS. Now it's running stock, and the voltage is at 1.195

Temps look way too high for that voltage.

To be honest, id recommend shove to stock cooler on and give it a run with that, just for comparison.
September 30, 2011 10:44:43 AM

I agree with M. Perry. Try a different cooler. Also refer to your mobo manual what those beeps mean.

80 degree's might not be "dangerous" but when the recommended is 73 degrees or under - its slightly "worrying". Certainly wouldn't be happy if my i5 was pushing past the 70 degree's mark.

I think I may have found *a* problem, but not necessarily *the* problem.

I tried running BF3 again, and kept an eye on my CPU temp (alt-tabbing out each time I died to check on it).

About 7 minutes into the game, I got the beeping from the computer again, and Alt-F4'd out, when I noticed something - the CPU fan was showing 0rpm in AISuite!

After a few seconds, the RPM went from 0 to 2000+, and the beeping shut off.

I'll have to check the actual fan next time it happens, to see if it really is stopping, or just a software problem. Any thoughts?

Ok, it seems that it's the CPU cooler beeping, not the motherboard.

When it started beeping again, I quickly checked the fan, which seemed to be running fine. I then checked the LCD screen, which was showing around 58°C. There was some kind of exclamation mark in a triangle, but I didn't want to leave it beeping while I checked what it was so I quit out of BF3, and the beeping stopped after a few seconds.

Take the side of your PC case off, and play BF as you normally would. With the side of the case off you can keep a visual eye on the CPU fan and check its still spinning and isn't cutting out or anything like that. Better to see it yourself than trust your PC to tell you. That way you KNOW exactly what is and isn't working.

I think I may be all right for now.
I took the radiator off the case, and removed the fan from it, and gave it a good clean out with some air duster. Ever since, it seems to be a bit better. The idle temp is a couple of degrees lower, and it doesn't seem to climb so fast any more when under load. I haven't tried any prolonged gaming to see if it stays below 80°C though.

I think I'll buy a better fan for it, just to make sure it stays cool. I have seen people recommend this one, but it has a 3 pin connector, and the stock fan in 4 pin. The Scythe comes with a 3 pin to 4 pin adapter, but do you think the CPU cooler will still be able to regulate the fan speed?

You need a 4pin PWM fan in order for the system to change fan speeds. Otherwise they will just run at max speed all the time.

Yeah, I asked on another forum and someone pointed me towards this fan. I've picked one up to try, but I don't think I'd be able to have 2 in a push-pull configuration, because of the way the CPU cooler works. It has 2 4-pin connectors, one goes into the motherboard, and the other hooks up to the fan on the radiator. I can't use a splitter, because apparently it would mean both fans would be sending the motherboard/CPU cooler tach readings, so it would flip out and think the fan RPM is wrong.

Which means either buying a fan controller (not really worth it) or having one of the fans running full speed all the time.

When using Push/Pull for CPU cooling, its recommended to have 2 identical fans both running at the same speed and both with the same CMF.
October 5, 2011 12:25:30 PM

Well, I bought one of the Vipers, plugged it into my CPU cooler, and the cooler wouldn't turn on. I don't know if the fan is drawing too much power or what.

So I've plugged the new Viper into a motherboard 4-pin socket (so it's essentially a chassis fan), and fixed it to the radiator. I put the original CPU radiator fan on the other side, as the pull part of a push-pull setup. I know you said to get 2 identical fans for a push-pull configuration, but I have to keep the original fan plugged into the CPU cooler to stop it flipping out and telling me there is a CPU fan error, and I don't know what else to do with the new Viper fan.

I also flipped the 200mm fan on the top of the case, so it blows air into the case rather than drawing it out.

I tried a stress test using Real Temp and Prim95, and got a max temp of 75°C.
I ran BF3 for about 15 minutes before I got bored, and my temp hovered around 65°C for quite a while, and maxed out at around 72°C shortly before I quit.

There is space on the case for a 80mm fan on the other side of the motherboard, which would blow air onto the back of where the CPU sits. Would it be worth putting a fan there, and if so, should I make it push or pull?

Also, there is another spot on top of the case, for a 120mm/200mm fan. Should I get one for there, and make it push or pull?

Max temps of 75 degree's look fine, I wouldn't worry too much more about cooling.

Adding a side fan might show a 2-3 degree decrease, but nothing major.

Having a good clean out/re-build might be a good idea. Based on the screenshot you posted, everything looks very dusty. Fan filters are highly recommended to keep the inside of your system clean.
