OK, and are you doing something special with them or they just "stand" there? For how long have they been running like that?

One's my webserver, one's my fileserver. The webserver has been running like this (on a broken motherboard) pretty much nonstop for about a year and a half. The fileserver is relatively new (and having some wicked X troubles), but seems to be running along pretty well. |

Right, thanks. So....I think I can run it as it is BUT it would be nice to get some chassi fans too, since I'm going to use my CPU much more then a webb or fileserver dose. Thanks, again!

GODDAMIIT!!!! I can't stand it anymore! This time, I was compiling k3b and playing with KDE when the computer just shuted down and sounded exacly like an ambulance!!! What is it about?? Anyone else with this ambulance problem??
p.s I'm not joking...

taskara, do the fins on your 7+ heatsink almost touch the fan or is there a gap in between? On the 7+ I have there is a significant gap, I'm wondering if they started making them cheaper after a while and I got a cheaper version of the 7+. My 7+ is outperformed by both a volcano 6+ and a 9. The volcano 6 is probably the best design as all the air is forced through the fins and it's slightly rectangular, unfortunately it doesn't have an 80mm fan on it (nor is it copper). The 7+ is not pure copper as mine quickly turned an odd color and it's not the color of oxidized copper, it is very heavy though so it must be at least mostly copper, maybe it's coated with something but it looks copper when you take it out of the box. I modded my 7+ so that the fan is now touching the fins on the heatsink but haven't bothered to try it since I did that, I currently have a 6+ with a manual fan speed controller on one cpu and it's working quite nicely (very quiet when I turn it down). Another system is using a 9 with a quiet 80mm fan on it and that's also working fairly nicely. The 7+ I was shipped using a quiet 80mm fan ended up with a temperature of 62C, putting the same fan on the 9 ended up around 50C, allways using silver heatsink compound. |

If you're worried, don't bother with your heatsink fan so much. Instead get a better case front fan (Antec makes some quiet ones that push a decent amount of air) and move some of the clutter out of the way (I use electric tape to stick cable/wires against the case side) so you have a clear path of fresh cool air coming in from the front of the case. Airflow is just as important as the heatsink stuff. |
Good advice, removing my (slow - Panaflo 80mm L1A) front fan makes my CPU temps go up about 10C. (from 32-42, approx) This is an Athlon XP 1700+ running at 2.0ghz, with a Volcano 7. Works well enough for me. 
Most motherboards report pretty incorrect temps anyway... Don't put too much faith in them. |

yeah there is a gap... but I have done some tests in the past, and found that the gap is actually better.
the reason is that the air in the gap is what's pushed through the fins.
think about the fins on a fan. it's not the air above the fan that's pushed through the fins, it's the air on the other side of the fin, ie between the fin and the heatsink. once that is pushed through, move air from the top comes down.
but the volume of air that you can push through, is limited to that tiny amount under each fin.
if there is a gap, sure some air will go out the sides, but the volume of air able to be pushed through is about 4 times that of a fan sitting right on top of the heatsink.
There is a balance of course. you can't have the fan too far away  but the volcano 7+ really only has two sides where the wair can excape out the edge, because of the metal bracket holding the fan above the cpu.
u can test it for yourself and see! 
secondly, it may not be pure copper, but it's 100% copper, meaning it doesn't have an aluminium core to sit on the diode, and then goes from aluminium to copper for the base and fins.

the siren is the motherboards warning to let you know it's over heating.
did you put thermal paste between your cpu and heatsink? if so what did you put there and how much. if that is not done correctly, then the heat can't transfer fom the cpu die to the heatsink, and it will overheat.
what is your voltage set on? it shoudl only need to be 1.65, or 1.7, even if overclocked to 2.2ghz.

this was true before amd built the temperature sensor directly into the cpu.
the motherboard gets the temperature directly from the cpu now (so long as your mainbord has this enabled)
I agree that before, when they used to use thermal diodes, that the temperature was a bit shakey.

Well I've got an Athlon 2600+ Barton on a Abit NF7 with a EKL Blade XP heatsink and under full load it never goes above 55 C, not sure about idle as I always have Folding@home running. The heatsink fan apparently goes up to 4100 RPM but is at the moment not going above 2600 RPM.
When I first built this machine I had a problem with overheating, the CPU was getting up to temperatures of 70 C plus, with just the BIOS running! Turned out I had used too much thermal paste when I first built the machine. I won't make that mistake again!
So the temperate you're getting seems fine to me.

Right...
But what about the crashes and sound of an ambulance when running e.g burnK7 (aka cpuburn) or stress?

A friend of mine pit the thermal paste there, called arctic sliver or something like that. And he knows what he's doing...It also seems to work, since I never go over 56C degrees.
No overclocking involved, just standard 1.83Ghz.
And the siren doesn't start when just using KDE or watching movies, last time it started (without me trying to start it by running stress or cpuburn) was when I used KDE, VmWare and compiled k3b at the same time. CPU had about 55C that time.
Also, it happens as fast as I launch cpuburn and the temperature gets over...hum....42-50 degrees, really hard to define. But I'm not sure if it has to do with the temperature... More with FULL (100%, not 99%) CPU load, a kind of 'shock' as when start cpuburn or compilation of a Qt app... What can it be??

hmmm.. not sure mate..
that sound is usually the warning sound for a cpu overheat..
check the manual or onthe internet, and see if they have informatino about the siren.. it could be memory crapping out or something..

I don't agree with your logic. The closer the fan, the more air is blown through the fins instead of around the fins. All well built high performance fans are either touching the fins or are in a casing of some sort which forces the air through the fins.

You can usually disable the heat alarm in the bios. Or you could just disconnect the pc speaker. I don't recommend either of these though as there may actually be a problem.
I've seen a guy leave the sticker on that covers the thermal strip on a stock amd fan (how stupid can you get?) and the cpu was still only running 60C. I think someone would have to put a hell of a lot of thermal compound on for it to create a problem but when you do apply the stuff remember you just need enough to coat the surface so any imperfections between the cpu and the heatsink are filled in, any more is defeating the purpose.
You might want to take the heatsink off and check it just to make sure all is well. Sometimes people start off with a stock amd heatsink that used thermal tape and then they go to a new heatsink and they don't clean the thermal tape crap off the cpu properly before applying the heatsink compound which can cause gaps. |

Well guys, I fixed it
I had to reset the heatsink...something went wrong first time I put it there. But I still don't understand why it died on 55C when I sat the overheat protection in BIOS to 110C (!)
Anyway, it's fixed And I'm soooooo glad

My Tbred 2200+ runs at about 60C idle, 65-70 with 100% CPU load. I've googled around, and it seems to be a little high, but not alarmingly so. My BIOS shutdown temp is at 80C.

40C idle - 45 full load Really happy with that, especially that I have bad airflow in the chassi (only one side chassi fan).

Try resetting your heatsink. I'm sure it would help! I thought too that everyting was perfect with the heatsink and temperature was quite ok for an AthlonXP 2500+ (55 at full load) but after resetting I see *huge* changes!
