Overheat issue

Hello everyone

I'd like some help with this as since i had this pc built i've lost to much time with it due to little things so i was hoping this might be something fixable without new parts...

The main parts..

2x 8800 GT inno 3d SLI cards
4x corsair dominator ram
Asus Striker 2 formula m/b

Well, i've been playing it fine on fairly taxing games such as AoC, one night i played from 9pm-6am but recently, i moved my room around, the pc is now on my desk against the wall, i ran it fine one night, then the second night, it cut out and said it was overheated and thats why the pc cut out.

So i downloaded the Nvidia tools to add to the control panel where you can alter your fan speed. i had it at 100% on both but still it turned off during gaming and got extremely hot.

I've had a look inside, i can only assume it's coming from the upper 8800 because thats the only one that has heat around it and heat on the case. (the power supply is hot but i heard that is normal) THE WEIRD THING is that from what i can see the fan is spinning...so i am lost

Despite not knowing anything about pc's and bios i looked for the temperatures. it said "SB overheat" on the first screen when the pc starts up, so i continue onto the hardware monitor and fine SB is at 90+ and the max for it is 100, i don't want to raise the cap because it hasn't done this for much more intensive gaming sessions so i assume something is wrong...

Can any of you much smarter people offer suggestions? hoping it's not to do with the asus striker as with the shit i've had with this board this'll be the final straw before i blow money on new stuff and smash it repeatedly.

Thanks!

u have cooling for ur case and coolin for ur cpu rite?

check for dust and clean it out

u said u moved around ur room
did u put ur pc next to a heater or sumptin

Are all intakes & exhausts clear? If you put it up against the wall, there may not be a big enough gap for air to get into your pc and cool it off. Make sure you're not blocking any vents.

Yeah there's cooling, and no dust.

Here's a picture of where it's located now.



btw been on the internet all morning and just doing this seems to be no issues and its quite cool back there...but when i game i guess thats when it starts to have problems.

The SB stands for South Bridge. Even though you think the area where you moved your computer is cool, it may still be not as cool as the place it was before. Hence, the South Bridge is not being cooled as fast as before.

You say you have cooling, but, if you haven't added a cooler I would suggest buying a Zalman cooler. That worked for me.

You could kick up the warning level, in the BIOS to, lets say, 1.07 or disable it. It could also be the voltage is not high enough. I would contact ASUS tech support about the problem. Let them tell you where to set it. Also, this may be the beginning of a signal that your mobo is going bad.

Also, try the forums on the ASUS web site. Others are probably having a similar problem and there may be a solution posted.

I'd say it's purely a siting issue. Move that PC back 6 inches from both walls. It may look untidier, but there will be room for air circulation.

I have the same problem: Wives don't like computers in sensible places

While this is highly possible(and i hope it is this...)
I have a damn good fan inside my pc, and last night when it cut out both cards were running at 100 but it still got hot towards the bottom of the pc(where the cards are) but not all over...could it be because of the place?

Before it used to be under my desk, nothing at either side and a little away from the wall, i hope this is a solution to it but i don't wanna get excited that i can sort it with some moving...do you really think it could be a siting issue? i guess it would make sense since i have not had an issue like this in all the extensive time i've had it in the other area.

Anyway, sorry if this post doesn't make so much sense, but i just turned 21 and am a little drunk

Your southbridge is getting to 90C? Umm.. what?

Your GPUs are at 100? Umm... what again?

Move the PC away from the wall, and ensure that your voltages are within normal operating parameters. Also check to ensure that all fans are fully operational in the PC, and that your power supply isn't overheating (this would cause voltage issues if it is severe enough)

Nah it was just the fans set to 100 on the nvidia control not the actual temp.

I've moved it away from the wall, hopefully enough, now i just wait and see.

Having had the same problem, "a damn good fan" isn't enough. I solved my problem by buying the appropriate Zalman cooler for my video cards. It worked so well, everything ran at a lower temp, cpu, etc. I suspect, although I can't vouch for this personally, that a cpu cooler would also solve the problem.

Heat rises. It is possible that the slight difference in placement, sitting on the floor as opposed to your desk, made the difference in temperature. I suspect that your rig ran hot even sitting on the floor, but, not hot enough to trigger the warning. This would further support the need to spend the $40 on a cooler.

I chose the cheapest approach because there are many options for cooling. Go to some forums and read how satisfied people are with their cooling solutions.

Your problem may simply be that you're not exhausting warm air from inside the case fast enough. Is there an exhaust fan on the rear of the computer? (other than the power supply and gpu fans?)

The Southbridge (which is one of the motherboard chips) shouldn't be getting that hot. It may be a cooling issue, but it could also be a bad power supply, or bad motherboard.

well, the OP is having a "southbridge overheat" problem. southbridge handles all the IO for the computer, which means it handles things like harddrives, CD drives, USB connections, etc. southbridge overheating shouldn't have anything to do with graphic cards.

check and see if your southbridge chip is being blocked off or not. it should look like a large silicon chip on your motherboard, but it could be under a heatsink of somesort.

From the looks of it, I am with Rahja: the rear of your PC is too close to the wall. You should have at least 4-6 inches between the wall and the rear of your PC.
