CPU Overheating?

By dragonrider69 ·
Hello, I seem to be having an issue with a Gateway laptop. The core temperature of the CPU is 75C this is extremely hot. I happen to notice when the power settings are set lower, of course to extend battery life that the temperature drops. Of course, this is also due to the decrease in performance from the CPU. However, I cannot seem to figure out why while in High Performance mode this thing gets so hot I could cook a pancake on it. Fan seems to be working, because I can hear it, and I have attempted to **** out the vents. It is an AMD turion CPU dual core of course. Therefore, any ideas would be great thanks.

That's not overly hot for a NB CPU

by OH Smeg Moderator In reply to CPU Overheating?

NB's get hot and do not have a lot of Heat Dissipation Possibilities so it's not uncommon to see Hot CPU's and HDD.

I've seen NB's which after running for a while get so hot in the HDD that it's uncomfortable to touch the Track Pad. However with every NB that I sell I advise the buyer to get a Cool Pad like this one from Antec

These have fans in them and connect to a USB Port. They suck air under the NB preventing the unit from having the Air Intakes blocked by paper, material or anything and because they suck the air through faster than the Fan on the CPU they also suck away any Air Borne Crud that would otherwise end up in the CPU's Heat Sink.

I personally do not guarantee any NB that isn't used with a Cool Pad and while they do shorten the battery life they are worth the decreased Run Time on battery by providing a better more stable and cooler NB.

The NB's that I've had complaints about being hot simply do not produce any complaints when there is a Cool Pad Fitted.


edited to add OH and next time you want to find out an answer I would suggest you ask a Question. Those who haunt the Question Threads don't very often look in the Discussion Threads so you miss a lot of possible answers.

I second the above.

If you're not experiencing trouble (sudden repetitive crashes f.ex.) then it's probably working within it's specs but would benefit from a coolpad.
If it's been in use for a while, it might also help to clean it out, especially the CPU fan, the CPU heatsink, the exhaust fan and it's vent. Have to open it up for that, just vaccuuming the grate can kill the fan.

definitely agree

by ozonedman In reply to I second the above.

blowing out the vents will work if it isn't real bad, but if there is a LOT of crap it can actually put debris in the fan and stop it. I clean every one I work on, and some have to be completely disassembled to get everything out. Newer cores run a lot cooler than they used to, first thing to check is the heatsink plugging.

I've experienced just the opposite - the new thinner wafer multi core CPU's not only pull half the wattage, but run run 50 degrees (F) cooler because of it. A 45 watt cpu is not going to run nearly as warm as the 135 watt predecessor, whether in a NB or a tower. Start overclocking and you change all the standards, and probably void your warranty.

Overly Hot.

by dragonrider69 In reply to hotter?

No odd behavior has actually happen from this until last night. It shutdown, and the temperature was registering about 78c to 80c. However, I have not really attempted to clean it that well. So giving that said, I shall try that and go from there. In addition, we do not use any type of cooling device, so that alone should help. With temperatures at about 78c to 80c, I cannot help but think there is something else going on here. Perhaps a very dirty board or damaged heat sink I do not know. Thanks for responses.

Also it could be a BIOS Setting

by OH Smeg Moderator In reply to Overly Hot.

I would be looking in the BIOS at what Temp the system shuts down.

I think you'll find that it's set to about 80 C and when it reaches that Temp it shuts down to save the CPU.

Of course if you can not set it any higher you have a problem but most times just moving it to 85 C will do the trick.

I don't see info on your background in your profile

by AnsuGisalas In reply to Overly Hot.

but if you're not comfortable opening the case and prying out the keyboard wafer to get to clean it, take it to a pro. It's routine for pros, but a scary adventure for the common man.
Scary adventures can be fun, though.

even the pros have those days

by ozonedman In reply to I don't see info on your ...

I recently had to change the cooling fan on an HP laptop, new 17" - forget the model. I actually had to disassemble the entire laptop, remove everything from top to motherboard. The fan, either to clean or to replace, was literally the last item you got to. Then, of course, after I get the fan part number and order one from Hong Kong (none available in the US for a reasonable price) it had to be reassembled until the part came in.(had a bad armature that vibrated bad but still worked.) Then the whole thing again. This would most assuredly be an adventure for a novice - but they aren't all that bad.

Haven't pulled a

Sony Viao apart recently have you?

They are just plain nasty to do any work on.

Talk about Poor Design completely dismantle to get to the HDD. That is one of the most common things needed with any NB. Even if it's just to get Data off a drive before you rebuild the OS it's easier to remove the drive and Slave it.
