I hope this is ok to post this here....

I have got a shuttle sb77g5 or something like that with a pentium 4 560. One day out of the blue it started to over heat, at idle and boot up the proc runs at 80c. I am not overclocking, i do have thermal paste and the hsf is locked down tight. I have even gone as far as buying a new proc to see if it is the proc. I have even tried underclocking and will still run 76-80c. I have reset the bios and even bought a new bios chip. Shuttle care is ticking me off, it has been 4 weeks and numerous e-mails and have heard nothing from them. I am stuck with lots of money just sitting here. Has anyone heard a problem like this or have a solution. I am in desperate need to get this shuttle backup in working order!! Thank you!!

Is anything preventing the exhaust fan from spinning properly? And if its not an issue with the heat sink making proper contact with the CPU, then maybe its an issue with the heat pipe making contact with the heat sink base... Can you take some pictures of the CPU cooler and post them?

my sb95 didn't have such problem. I am running intel 640 cpu with their hsf. I however, didn't use shuttle's thermal grease, but rather I use the thermal grease from thermalright (that comes with xp90). I have read that using a better thermal great will help greatly. Maybe you want to try use like artic silver and such. Also, you might want to try to go into bios and change the cooling options to allow the fan to spin faster(I have my temperature for the system set as 35 degree) and during the idle, it will hovering around 40ish degree for the cpu and the mobo.

I'd be willing to bet that Justin nailed it... check the heats sink fan to make sure that its spinning. If it is, remove the heat sink and reapply the thermal paste. While you have everything apart, take a can of compressed air and blow the system out really good to clear out any dust

i have done all thee and above. I have the fan on all the way, and besides once it gets up to 76c it turns to full any way. The one thing i havent tried is artic silver 5. But that wouldnt make that much a differance between 1 and 5. I have checked the connection between the heatpipe and the heatsink and there is nothing loose.

here is a pic for those that dont know what the hsf looks like.

I appreciate the help so far, thank you.

All I can recommend is reapplying the thermal paste, check to make sure the HSF is seated properly, and to check that the voltages are set correctly in the BIOS for your particular CPU.
Something has to be causing the CPU to overheat. If the HSF is seated properly, if the fan is spinning and there is good air flow (if you are running it with the side panel off that should be fine), if the thermal paste is applied correctly, and the voltages are right......then I'm stumped.

What about the ole 'touch test'? Not to encourage you to burn your finger, but if the processor really is getting that hot, then the HSF (or the air around the HSF) should be very hot as well.

Here's my troubleshooting tips:

If the HSF does not seem to be 'that' hot, then it means one of two things:
1. there really is no temp problem, but something about the shuttle thermal sensors make the system think it is overheating.
2. there is a temp problem, and something is preventing the heatsink from properly dissipating the heat generated from the processor (if you have an external thermal diode around the proc, get it out of there to make sure it is not hindering heat sink contact, or there is such a thing as using too much thermal paste... make sure only a very thin layer is applied to the processor.)

If the HSF is very hot, then it could also mean one of two things:
1. since the heat is dissipating enough to make the heat sink very hot, then the contact with the processor is not the issue, make sure there is good air flow to ensure proper cooling of the heat sink. Maybe take a box fan or desk fan and position it to blow through the heatsink.
2. The last thing I can think of is the motherboard is sending too much voltage to the processor. This could be a bios setting or that the motherboard is just plain-old going bad. Is there a place in the bios for 'system health'? and if so, does it show the CPU volts? if so, post what it says here and some one will be able to tell you if its too high or not. If the board is bad and sending the wrong voltage to the CPU, not sure there is any way for you to fix it. If its under warranty, it might be time to think about an RMA. If its not under warranty, then its a paperweight.

Hope this helps...

all i can say to that is something that is nearly 200f is really freaking hot and burns like crap!!!! split second on the heat sink burns!!! lol

and thats the thing, i have tired sending RMA, calling, e-mailing and nothing, i feel like i am talking to a frys personel. (sorry for anyone here that works at frys) LOL Shuttle will not talk to me. I wonder if they are registered with B.B.B. LOL When i get home i will post the voltages.

check out htis forum, it has a lot of info on the shuttle's system. Do a search of your modle to see what other people have experienced.

SORRY, forgot to post the forum:

yeah, it definitely sounds like too much juice is going to the poor processor, good reply btw Justin. you just added something to my checklist, lol (didn't think about the touch test, just more used to feeling out the system heat near the CPU, but that's in desktops).....am I mistaken, or does that look like an aftermarket cooling solution? Sometimes we can make mistakes and match the HSF and chassis incorrectly if it is. If not, then they must have updated that chassis, and will have to do some research on it.

Hey man, I brought up the voltages!!!!! LOL

OH crap, my bad, lol; mind is shot from all that Cisco, rofl; you can discipline me with the bamboo cane later, rofl

It happens all the time....hell, everyone pretty much ignores what I say anyway.....
Still, go hang your head in shame for 10 minutes, or better yet go watch "A History of Violence", that should be enough punishment for anything you have done or ever do in life (A God awful movie)

Does "The Exorcist" count? Seeing that preacher get flooded with green pea soup puke is enough punishment for me, rofl. Now this should serve as a good lesson in life: never creat a past where you repeatedly abused neurotropic drugs (read weed), lol.

lol omg you guys. lolololol

ok its a P4 550 @ 3.4
ok here are the voltages...
cpu- 1.31v
agp- 1.47v
ddr- 2.56v
5vsb- 4.89v
voltage battery- 3.16v
cpu clock- 200

ratios or whatever... 66/33/100

i have the shuttle with me here at work so anything would be greatly appreciated!!

i also found this. I am working on my electrical engineering degree in college but havent gotten this far yet. Also shows what teh inside of p4 looks like, kind of...

Okay, your voltages look fine. What it comes down to, in my opinion, is that your heat sink is faulty, or not installed properly, or the thermal paste isn't applied right.PM me all the pertinent information, and let me try my luck with Shuttle.

my thinking exactly

**UPDATE**

Sorry too bring back an old topic, for those who care, lol

First off i want to thank yall for helping me with that and putting in a word to shuttle to get them to actually talk back to me!!!

I finally recieved the shuttle back today and didnt have to pay for anything except shipping. Well the saying still goes, "you get what you pay for" After opening the shipping box and the shuttle case they just replaced the motherboard. After further inspection the didnt return one of the locking spings for my heatsink so now i only have 3 to lock the heatsink down. And they didnt fix the problem, actually it is worse. Instead of it being 80c at idle it shoots to 103c and shuts off. Thats even after using(wasting) my 11$ Artic Silver 5 on it. I e-mailed them today and so now i am waiting for a response.

DONT BUY SHUTTLES!!!!!!!!!!!!!!

i am so sorry to hear your experience. It's kind of weird that you keep getting the same problem even with the mobo being replaced. Did you apply the right amount of AS5? If you apply too much, it's not good. Also did you put the whole cooling apparatus correct?

LIke I said, I have no problem with my shuttle. OH, btw, I also have update the bios and enabled the cooling feature under bios to keep my cpu running cool for the most of the time. Did you have that enabled?

Alright, I'll shoot them another email....this is ridiculous. i'm really sorry for your experience, but we'll do what we can to help out.
