Too hot CPU?

opivyattack · Post by **opivyattack** » Sat Jun 25, 2005 12:07 pm

ok well I was running a hot CPU so I reinstalled the HSF thinking it might have been my fault.. This time I cleaned everything off and installed AS5.. Well im still getting just about the same temps.. between 60-65C idle.. Is that hot? Gaming im getting about 70C or so. Im using the retail AMD HSF which runs at 3100rpm for an AMD Barton 2800+. I also have what I believe is sufficient case airflow.. I have one intake fan at the front of my case and one exhaust fan in the back of my case. My Antec PSU also has a fan on the bottom of it (in the case) and one blowing air out of the case (on the back of the PSU). According to my motherboard my case temp is 35C although it does run about 5 C cooler if I open up the case.. but then it is kinda loud and annoying.. Any help would be appreciated.. P.S. I believe Bartons are the hottest running processors available so im not sure if this is a decent temp.. but I dont think so..

What is the temperature in the room you're in?

Well Bartons aren't the hottest running available. The Bartons actually run relatively cool compared to the other Athlon XP cores. 60-65C idle is extremely hot if you ask me. I'm runnin a 2500+ Barton with a Thermalright SLK-800U and 92mm Panaflo fan which has a lot of dust build up and its runnin about 41C with a 21C case temp. How are you checking temps? BIOS? Motherboard Monitor? Is this the on-die temp gauge or the mobo temp gauge?

You certainly are running too hot with a 60C idle temp. Your idle temp should be below 40C or very close to that. A full load temp above 55C is a problem too. May I suggest a Thermalright Si97 CPU cooler and a decent 92mm fan? Also, your internal case temperature of 35C is also way too hot. You must get better airflow through that case, which may mean cleaning up the IDE cables, opening up the intake fan grill, and things of this nature. A side panel fan might help quite a bit, if you place it over the videocard / CPU area.

I don't know if you solved your problem or not but I in the same boat. I am running a AMD Athlon XP2600+ (Barton) and have gone through three aftermarket HSFs. Currently I have an idle temp of 45c with a system temp of 34c (via BIOS). I have the warning beep set to about 56c and the only way I can use the system without a Star Wars cantina band playing I have to use a duct going from the CPU/HSF to an exhaust side panel 80mm fan. With a box fan propped up on the mobo side blowing at full speed.

You can see the reason I am moving to a heavily modifed case with a water kit (120mm radiator) installed inside. I hope that this will remedy the situation in my circumstance. Anybody have any other ideas??

si-97's rock; i found them to work best in full tower cases with the fan blowing in towards the cpu. it is tricky to work with them in smaller cases. every 3 months or so you have to take the fan off and clear the dust.

those PSU's with the extra fan pointing down are not the best idea if you are using a small case and certain boards (cpu placement) because it just pushes the hot air down onto the hs/fan.

keep the box on the floor and not with the back too close to the wall so it will have some room to push out the hot air away from the box.

i have found room fans to do best facing the front of the box and at medium speed on an open case panel(left side) it will create sort of a vacuum and pull out the heat. if you face it towards the board and the cpu fan is pointing out, then it will defeat the purpose of the cpu fan.

Some Athlon32's do tend to run hot, and some of them are also notorious for mis-reporting the temp.

I have two 2000+ rigs (using as Media Center PCs) and they both run at 55 - 58C at idle.

What I would recommend is that you actually reach inside the rig (after it's been running a while with the cover on) and touch the heatsink. If it's too hot to leave your fingers on it for any length of time I would be concerned, if not I wouldn't worry too much about it.

It would certainly be nice to get the temps as cool as you practically can.
- Re-arrange your ribbons to allow smooth un-turbulent airflow from the from to the back of the case.
- Don't go overboard with fans. A common mistake is using TOO MANY fans. This is often creates a worse situation since it can distrupt the smooth airflow. In addition to the PSU fans (and you SHOULD be using a quality PSU with 2 built-in fans - one on the back of the case and one inside the case. Anything less is not good enough in a modern rig designed for gaming), and the CPU fan the only other fan you should add (if needed) is a front intake fan.

I DO NOT recommend blow-hole fans unless you also use a shroud under the blow hole to force air through the CPU heatsink, and you use either a blow hole fan or a CPU fan but NOT both. Just putting a blow hole fan on the side of the case doesn't do much and often disrupts the air flow.

If you have a particularly hot running video card then you can also add a rear exhaust fan to the case (most modern cases are designed for this).

Hope this helps...
