AthlonX2 temps - this bad boy runs hot!

Had my X2 4400 running for a few days now; haven't really done the whole "cycling" thing to let the TIM break in...it's been running the whole time.

I have the stock HSF and after three hours of P95TT, max heat (2 instances) my CPU temp is 64C. Case temp is 44C. The thing idles at 52C.

I would assume this is normal due to there being two cores under there? The stock HSF is a pretty substantial looking heatpipe affair w/a copper base. Quiet, 2500-rpm fan, though.

Is there better cooling out there that isn't like XP120-sized?

Hmm, that doesn't look right at all. My 4200+ is overclocked to 2.475ghz with the stock AMD cooler, and only gets to 51c under load with 2 instances of prime95 running. I would make sure the heatsink is properly seated.

Something isn;t right. Could even be the motherboard sensors. My Abit has that problem(same cpu at the same speed in another mobo reads 15c too high in the Abit), but everything else in the house is OK.

Really? :confused:

Granted, this is my first time ever seating a Socket939 cooler, but it's all the same. Ensure the thing is seated and level, clamp it down.

I'm going to stop P95 right now.

Glad I asked! Thank you!! :thumbsup:

*edit*

Something IS NOT right. Within 5 seconds of stopping P95 the temp dropped from 64 to 55C. Not possible.

I am 99.99% sure the HSF is on there correctly....gotta be a motherboard glitch.

Err, the temp should drop after you stop prime95, but your idle temps are still too high. What motherboard are you using?

As long as you've seated the HSF right, don't worry too much about it.

My Venice gets to ~ 63 C under load too...'cept that i know it doesn't actually get that hot.

Sensors are wrong on my mobo, just like on MichaelD's mobo.

Yeah, they should drop, but not 9C in about 5 seconds. It's the EVGA NF41, which is made by Jetway. I'm using the Jetway monitoring software, which works perfectly. Reads the voltages and everything.

Screenie!

As i said, it's your sensors, don't worry.

Mine does the same thing. It'll jump like 15C in a few seconds, & drop down 15C in a few seconds also, which isn't even possible.

yes these babies run hot

with my slk948u, it was around 50-52 load with the side of my case open

this is with a 50cfm fan

voltage was 1.375x1.04

What case? You may be able to solve alot of the problem with good case airflow.

It shouldn't be that hot at all. Cross-reference your temps with several softwares, such as Motherboard Monitor 5 and SmartGuardian. Also, if it's REALLY 64C, then the heatsink area should be HOT to the touch. Put your hand near the heatsink (don't touch it in case it really is hot) and see if it's noticeably hotter than the rest of the case.

These things run cool until you start volting them....

At stock 2.2ghz I can run 1.3v and idle at 27c and load under 40c.....At 2.4ghz with ~1.35v I can idle at 28c and load at 44c max...At 2.5ghz with 1.42-1.44v I idle at 29c and load at 48c.....2.55ghz at 1.456-1.488v I hit 30c idle and load at 51c....2.574ghz with 1.456-1.488v I hit 30c isdle and load at 52c....


Right now in testing phase 2.618ghz with 1.504-1.536v I idle at 30-31c and load at 55c....

That is not bad when you consider I am over 10% overvolting at this point...

The heatsink is warm, but not hot. I believe the MB is flaky reporting temps. There's no way the temp can drop 9C in 5 seconds. Not possible.

The temperature drops 9C in a few secs because the thermal diode drops in temperature fast. It happens with a lot (if not all) A64s, that's nothing to worry about. It looks to me like your cpu temp is being misreported because your idle temperature is too high as well.

Again, what is your case model? Inadequate airflow will cause the problems you are describing. High idle, high load. Case cooling is every bit as important as a HSF.

2 rules of thumb for optimal heat removal:

1. Efficiently transfer heat off the CPU (= quality HSF and TIM)

2. Efficiently transfer heat out of case (clean cable runs, clear all obstructions as allows, adequate cfm fans)

Wow - that's friggin HOT!

I only get up to 49C with two Prime95s running. I idle at 36C, and BF2 gets it into the mid 40s.

To eliminate the case, take the side cover off, and have a small fan blowing inside the case. If the temps are the same, its your motherboard misreposting temps.

oh yeah, if u touch it and its not that hot, then its not that hot...lol

i remember back with my socket 754 dfi that my temps dropped 10c with just a bios flash...lol

so basically it was just reporting too high like urs

Thanks guys. I've got a full size (EATX) case. Airflow is good. 92 and 80mm intake, 120mm exhaust + PS fan.

It's got to be the MB.

I just finished an hour or so of gaming. Immediately upon exiting, my CPU temp was 54C. Got to be the MB.

The motherboard is the EVGA NF41...brand new to the NF4 arena. The EVGA Forums are very active and lots of folks have this board; EVGA is taking notes and is working on getting a bios update.

My previous DFI NF3 used to show my CPU temps shoot up 15C instantly upon initiating a P95 torture test. I suspect your sensors are about quirky as mine were.

Hey MichaelD,

Get tired of 2cpu ? j/k

Look at the XP-90C w/ a Panaflow H1B fan w/ a controller..

If you change mobo's , look at the DFI SLI-DR .

Regards,
Jose
