Seemingly obscene X2 3800+ temps under load

So i just swapped out my 3200+ for an X2 3800+, and am getting a bit concerned.

At idle, my chip runs around 44-50 degreez. which seems normal, my case temp is usually around 36-40

Now, the scary part, is when i run 2 instances of Prime, one on each cpu, the temp shot up all the way to 79!!!! That's darned close to the max threshold of the chip, no? What do you guys think is wrong? It seems weird that idle temp would be good, but under stress it would almost double!!

stock HSF btw. I did use thermal paste, artic silver 5, just applied it last nite.

Stock HSF is to blame. Get an Arctic Cooling Freezer 64 Pro, Scythe Mine, Scythe Ninja, etc for lower temps (guaranteed).

ASUS A8N-SLI Deluxe

any HSF that's quiet that Does NOT require removal of motherboard? really don't feel like doing that again. i had a stock HSF on my 3200+ and never had this problem :-/

Ditto here. My newly upgrade x2 3800+ stay @ 38c (full load) or 36c idle, using AC 64 Freezer pro and Zalman thermal grease.

The Freezer64 Pro doesn't require motherboard removal.

The stock heatsink is in no way causing those temps. What are you checking them with? Both MBM and HardwareMonitor reported my temps (on my old VNF4 Ultra, not my board now which the same as yours) as sometimes in the 70's, other times the 120's. But the BIOS had them firmly around 35C. So I'd get it into full load for a little while and reboot into the BIOS and check it out. Also, try using SpeedFan, because I'm using it on A8N-SLI Dlx and it works fine.

Word of wise...Always use more than one thermal sensor to monitor your hardware. I use PC wizard and mobo's bios to check the cpu temps.

heh my computer conveniently sits above an AC vent so i ducted it into my computer... I get temps ~27ºC... 2.8 isnt a problem but I tend to not have a dire need. ~2.6 (htt 260x10) is fine.

79 is quite high... not many people do enough to simulate an instance of prime on both cores though. new FPS games at high res only keep them around 60% usage. the vid card is another story.

You have a problem, man. Either you don't have your heatsink fully seated, aren't using any case fans, or have your computer in an unairconditioned room. Of course, download and install this, it's thermal sensor is much more accurate, it seems: SpeedFan. If you're still getting above 55-58°C while running two instances of Prime95, SP2004, OCCT, or whatever you're using to stress the cpu, you're going to have to buy some high output case fans, or buy a better heatsink, if you're already using good case fans.

I'm going to have call shenanigans on your 2C increase from idle to full load. Define 'full load', because my definition of a full load is having every core running at 100% for a while. At that point I see where the temps top out at. Maybe you meant 48 or 58C full load?

to the TC,

79C is well past the advised temp for your processor (65C for the ADA 110W chips, 71C for the ADV 89W; maybe the 65W or the 35W can go that high, but I doubt it ).

In any event, 79C is getting up into the thermal shutdown/damage your hardware range. If that temp reading is accurate, something is very very wrong.

Is the HS/F seated properly? making full contact with your CPU heatspreader? have you removed and reinstalled your heatsink without cleaning and re-applying thermal compound? is the heatsink Fan working?

44-50C idle is a bit high, but not suprising if you don't have an AC in the comp room. Is this the case?

Touch the heatsink when it's under load and reporting 79C, it should be burning hot if the chip is actually that hot and the heatsink is installed properly. If it's not burning, either it's not seated correctly or the sensor reading is totally off.

I'm pretty sure the chip would fry at 79C - the sensor must be out or showing a reading for another sensor.

Whoa that program is wild and I now know why my 4200 is limited to around 2.55Ghz....Core one is idling at 32C and core two is idling around 39C...guess i'm gonna have to pick up that AC freezer pro now since I think this baby has more left in her :)


Ya temp logged one core loads to 51C the other to 43C I just pulled the trigger on some AS5 and an AC Freezer Pro in hope that if i can get the one core down I can get up to and past 2.6 like I originally wanted since I can boot into BIOS at 2.87 but not windows.

Use atleast 2/3 prog's to check temp's as to make sure one isn't 'whack.' I did the same, but went from a 3500+ to the X2 3800+. Temps were not as high as yours, but they were too high for my tastes (idle 44C, load 56C w/ X2)....did some research...it has been documented that the X2 IHS's on some/many X2 3800+'s do not make the best of contact with the core. So I went at it...now I idle at 34C and load at 44C(ambient is 24C & note my pc is fitted with 4 800rpm 120mm fans). I don't recommend by any means doing this IHS removal, but thought I might enlighten some. Also this is not necessarily whats happening with you. I would again check the seating of your HS to the chip and see how the TIM is spread. I've had much better luck with the 'rice' sized dab and leaving it be...then seat HS and twist gently/rather then spreading a thin layer all over the IHS (with razor or plastic). Best thing IMO is to do a test. Clean up TIM on IHS and HS.... Re-apply....seat HS...remove and see how the TIM makes contact. Your case temp seems warm to me, but not to high to validate your load temps. Where is your Vcore at scarfase?
And to cmrmrc: yes that is rather common as far as core temp values differing by ~8C. Extreme systems has a big thread on it...srry don't have link on hand :).
