:thumbsup: Hello everyone. I've searched through the forum a bit and although I do see some hot chipset issues, nothing approaching Nortbridge temps going over 250 F like mine.

My system:

Gateway FX6800-01e i7 920
12 GB DDR3 Triple Channel Memory
750 Western Digital SATA2 7,200rpm
1 TB Seagate 7,200rpm
ATI Radeon HD 4850 1GB PCI-E x16
Corsair TX750 PS

I also added an 80 Antec 3 speed fan onto the side panel grill, just below the huge CPU fan snorkel, pointing at the northbridge heatsink.

Here is a screenshot I just took a minute ago. http://wesright.com/images/scrshot.jpg

SIW calls that sensor TMPINT01 and Everest calls it Aux, but I'm assuming it's the Northbridge chip. The heatsink does get rather hot, I can only put my finger on it for maybe 2 seconds or so before having to pull it off. 250 F plus though? I hate to say this but it's been doing this for pretty much the 18 months or so I've had it. I bought it at the start of 2009.

I can run just about anything on it. Modern Warfare 2 isn't a problem, Crysis runs great, Just Cause 2 is flawless, and I just tried Prototype the other week and it runs great too.
However, I can't get that temp to go down. I've Googled around looking for similar setups/problems but people seem to panic when their chipsets reach 80 C, wow.....I wish I had only 80 or 90C.

Any thoughts? Ideas? Anything? Finally getting tired of looking at this temp I'm going to take a ride to the local cables and connectors shop to see if I can get something to put on top of the heatsink.

My main, well...issue for lack of a better word, is "How can this run this hot without frying the motherboard?" Check the screenshot, the other MB temp is ok, the CPU temp is great, the video card is a little warm but hey, it's a Radeon. I just don't get it.....

"How can this run this hot without frying the motherboard?"


You have answered your question with the question. How can this run this hot without frying the motherboard? Answer: It can't. No chipset can take a temp that high for that long and not die a painful death. The fact it still hums along means you have a sensor that is flakey, or a phantom sensor that isn't even there. Just because the BIOS has a slot for another sensor, doesn't mean it is hooked up, and it will default to the low/high end of the scale.

I would just ignore it.

I'm thinking about buying one of those laser temp thermometers. <clipped>

Turns out my brother has one, I just pointed it onto the northbridge heatsink and its showing up at 174 degrees F. That's a lot better than 250 F but thats the heatsink. Wouldn't the chip under it be hotter?

Anyone have the Gateway FX6800-01e? I'd be VERY curious to find out what kind of temps others are getting with this same system. I wasted 2 hours last night completely pulling it apart just so I could bench the motherboard. With these kinds of temps there was NO WAY I would risk pulling that heatsink just to laser read the temp on the chip itself. I was able to get it running with nothing else even hooked up other than the video card. All it had to do was post, test the main memory and video card, thats it. I didn't even plug in the hard drive. I managed to get a reading from the edge of the chip under the heatsink of just over 200 degrees F.

I built my first 8088 XT system so many years ago that I'd rather not try and figure out just how many years that was, but I have NEVER seen temps even close to this. I can safely say this is INSANE. This thing should fry itself in less than 5 minutes.

Right now, just to see how it'd run, I'm pointing an 8in house fan through the open side onto the Northbridge. It's still at 90c (194 f)

I can't believe I'm still running it but the one thing that really irks me is that it works. The darn thing actually runs this way and I don't remember if I mentioned it or not (since I've been whining about the NB so much) the system is rock solid. I don't get any errors, at least not outside of the normal Windows nonsense. I even installed games I don't like just to push the system a bit more and nothing (Prototype for example). I played Modern Warfare 2 for almost 2 hours last night after putting it back together. Not a single glitch.

Enough of the senseless whining, sorry guys. On to something constructive. Has anyone replaced their NB heatsink solutions for something better, or just added a fan? I'm curious to see what I can find out there. Also, I'd REALLY love to see what someone else with an FX6800-01e is getting...

Thanks,

First, you should see if you can get this problem solved with your warranty. Doing the following will likely void your warranty.

I've never done it, but they do sell aftermarket northbridge coolers. You have to be careful when removing the old heatsink though; you risk pulling the chipset off. You also have to clean the old thermal paste off before applying the new stuff.
You can also get a PCI slot fan and place it in the slot just under the northbridge.

is it doing normal operation though. I would go through the Overheating Procedures.

I wish I still had the warranty but I bought this system at the start of 2009. The warranty is done unfortunately.

I had the motherboard out last night and I was going to pull the heatsink to at least clean up reapply the thermal compound, but umm.....embarrasing enough I started pulling it apart before I checked to see if I had any thermal compound left...sigh. Since it's transferring to the heatsink though, and not frying the NB, I'm assuming that whomever puts together the motherboards for Gateway did a good job with seating the heatsink.

I am going to be looking for active cooling though. I agree there, I can't leave it like this. I forgot about the expansion slot fans, thanks. The thing I hate is not being able to hear them first. I don't trust most mfg. db noise numbers but oh well.....gotta do it.

Thanks,

I mentioned it above. The system is running ROCK SOLID. Running Win 7 Ultimate 64 now and even ran various Linux installs without a problem. I don't understand it. I would completely disregard the sensor temps if I hadn't pulled the cover and touched the heatsink, as well as check the temp with a laser thermometer.

I ignored it since I got it in March of 2009. I thought this can't be real, just a bad sensor. The other day I pulled the cover and actually checked, and now it's freaking me out. I realize its rock solid, but in good conscience I can't leave it this way...<sigh>

UPDATE. :thumbsup: UPDATE.

I have managed to get the NB temp down to 89 C under a moderate load. It doesn't really go over 91 C even when I push it.

I was looking around for a better NB cooling solution when I came across a heat sink/fan setup I had used on an old 486 DX4-100 setup. I removed the fan becuase the heatsink was too thin to use. Now, I was much too paranoid about mounting a "years" old fan onto the NB heat sink because I can just imagine how hot the chip would get if the fan died and pretty much covered and insulated the top of the heatsink.

Solution: Someone here posted about using wire ties in an unrelated post, so that's what I decided to do. I tied the fan as close to 1.5 inches away from the NB heat sink as I could. This way, if the temps shoot back up to 250 degrees F then I'll know the fan died and I can immediately pull/fix it.

While I am not completely happy with the 89 C, I can relax a little and try and search out a better solution. Intel's data sheets claim the x58 chipset can reach 100 C max, so at least I'm under that now.

I doubt I'll be happy with a fan/heat sink solution, at least not one mounted on the heat sink since the system will shut down if the CPU temps shoot up too high, but it doesn't look like it will if the NB temps get too high. If it didn't shut down @ 120+ C, then it won't until it fries.
I'm going to try and either find or build a bigger fan to use as a replacement for this tiny 35mm fan. If a 35mm fan can drop it from 120 C to 89 C then for example an 80mm fan should hopefully bring it down to say 60 C. I'll probably have to build a funnel or tube of sorts to direct and concentrate the air onto the NB heat sink though.

Thanks everyone for your help and insight. I'm sorry but I forgot who mentioned using the wire ties, I'd thank them also. I probably wouldn't have thought of using them right away and probably ended up with something else.....
