is idling at 50 degrees Celsius odd for a 3800 X2?

[Accipiter22]

I have a 3800 X2 processor on an Asus A8V-Deluxe Mobo, and it's idling at about 50 degrees celsius...I'm not sure if this is too warm or not? I know dual cores run hotter, but I'm not sure how much hotter they're supposed to be

yeah that sounds a bit hot - my dual core opty idles at around 26 degrees celsius - wot are u using to measure the temps? wot cooling are you using? Voltages?

 

[Accipiter22]

stock voltage, stock cooling fan, and using Asus Probe to measure temp....I'm about to start up Civ 4 and see if it runs much hotter under idle...it's running at 52 celsius with Super Pi but I suspect that Super Pi doesn't load a dual core the same way it does a single core

It really shouldnt be getting that hot even under stress - when you fixed on the stock HSF did you replace the crappy 'thermal pad' with some proper thermal paste? It might be worth buying a third party heatsink if you cant sort it out - you might damage your CPU if you're running too much hotter (eg 60 degrees) for prolonged periods - is the temp measured in the bios or do u access it through windows?

accessed through windows, via Asus Probe (it's a program that came with the A8V)...I'm using Arctic Silver 5...maybe I didn't use enough.


Oddly enough, under load it runs at 53 degrees celsius...so it only goes up 1 degree...not sure what ot make of that

Check the temps in the bios - they should be more accurate. If not, I had a similar problem with a 3500 about a year ago, but after reseating the CPU and reapplying the paste and HSF it seemd to work much better

My X-2 idles at 39C according to CoreTemp (hottest core). PC Probe reports 27C. Is this normal? Running Orthos it says 57C (hottest core). I'm using stock cooling with cool&quiet on.

same thing. I just reapplied the AS5 and it still idles at about 49-50. Now sometimes AS5 takes a while to 'settle in' but still, even then I should be getting lower temps I'd imagine. I'm using the stock heatsink/fan from my 3500+, but it's the same sink/fan they use for the 3800, so I'm not sure why that would matter. Is there any way I could maybe manually force the fan to spin faster or something?? Again when it's under load though it doesn't even really go up more than a degree or so celsius, it just starts out hotter. what gives?

The only thing I can imagine is that the HSF is just not cutting it - if the CPU is massively overheated in the first placfe, then running it under load wont make much difference to the temps - AS5 is only going to give you 2 degrees or so improvement anyway - it might be worth getting hold of a better heatsink - im using the thermalright xp90 which works wonders. A quick thought tho, maybe try reversing the air direction of the fan above the CPU - I have mine blowing down on to the CPU which also cools the surrounding parts of the motherboard

Or use coretemp?

 

[sdifox]

you sure your hsf is mounted properly? I had similar problems (actually worse, machine would shutdown with thermal warming) and it turns out I installed the clip upside down. Flipped it over (after cleaning and reapplying past on cpu) and voila, no more temperature problem.

 

[Accipiter22]

well I left it running over night, maybe the AS5 had to spread out more or something, I'm idling at 40 degrees celsius now

 

[Accipiter22]

under load now it will go up to 50, but comes back down to 40 pretty quickly after the load is off, so that's good

 

[LOUISSSSS]

depends on your room temp.. 3800x2 can idle in the 50's if you're in the southern US where its really hot...

Sounds about right. I idle at 41, hits 47-51 under heavy load. With all the stuff in my case I'd say thats pretty good.

 

[Accipiter22]

idling at about 35 now....guess the AS5 took a while to spread out well.

 

[Smartazz]

For one core being stressed, that's fine. When both of my cores run stressed they hit around 57C on stock cooling.

Really? Get XP90 get both cores at 29 degrees C max!!!! Thats 1.51V with 65% overclock - fork out the $40 extra!
