overheating when booting with fedora core

[gdashafe101]

I have a machine that i built (3500+ amd64, 2 gb ram, geforce 6800 graphics) and i do have a buttload of fans in there with a 550 watt power supply. I am dual booting with windows xp pro and fedora core 3. It overheats sometimes with windows when playing a system hog of a game but when i boot with fedora core 3, it gets hot really,really fast. i have no idea as to why it would do this and any help would be greatly appreciated. thanks.

Just wondering if your motherboard has the capacity to step down the power to the processor when not fully needed and that's Windows drivers involved? You might look at some of the super-cooler fans for the processor, plus double-check the flow around the box. Sometimes too many fans create actually create back-washes and eddies that can increase internal heat. I had one system where the back fan on the box was too close to the power supply and negated air flow through the supply itself. Also, tying up and re-routing the cables can help air flow, as I'm sure you know. Lastly, with all those fans, you may be sucking in more dust bunnies than the family Hoover. Might want to check periodically for build-up.

This is the first thing to look at - you have insufficient cooling. Whether this is due to too fwe fans, or whether it's down to incorrectly designed cooling, we can't tell. But you ought to fix this (look particularly hard at how hot air exits tyhe case - if it recirculates, it won't cool next time it goes through the heatsinks).

Check that your fans are actually spinning. Some motherboards (e.g. my laptop) require an ACPI command to start the fans. This is why that laptop runs Ubuntu...

1st choice: Since you spent so much money for a high power system get also watercooling will cost you 200 € more and you`ll have it for lifetime.

2nd choice: As previous guys said... Keep your case tidy and with free space.
Basic aspects: a) Warm air is lighter so goes up cold is heavier thus stays lower. This means that the air entering the case is cold then gets warm and moves higher. (translation) Fan take the air from low and put it in the case.The air gets warm by systems temperature and goes higher where fans take it out from top of case.This way you have a flow of an air cooling current.

b) The air that enters the case should be no more than leaving the case.
(translation) If you have 3 fans pushing air inside and 1 taking out you can understand that air fast comes it side ,it gets warm and then only a small amount of it gets out. Which means your fans are useless.
(i dont have to mention that there is no mistake all fans putting air inside or all fans taking air out)

c)Have your case uncluttered. Tidy wires= spacy case, no dust ,keep it in average temperature areas.

d) The connection between cpu and cooler must be tight,with only 1-2 mm of silver cream layer. If you empty all the paste on the cpu and set the cooler the heat is not transfered so u get insufficient cooling.

e)put a fan on the northbridge chipset also...if it gets burned then graphics,memory are not working properly.

Good luck !!!
