CPU Temps Just Shot Up

[MyRep]

My CPU temps have gone form the high 30s to 49-53 over the last two days. Any hints?

XP 2500+ stock settings, MSI k7n2 Delta ILSR, ATI 9800 pro, all fans and air intakes clean and working. Bad azz SLK 900A cooling. Enermax 460 PSU. Room temp consistant. M

Everything was running fine for 6+ months. These spikes just started.

What do you all think?

Did you start running a DC project two days ago?

 

[MyRep]

No DC projects...that I know of??? Checked Task Mgr and no CPU usage, checked Zone Alarm and no apps accessing net. Ran AV for trojans and Ad-aware for spyware all negative.

Anything I missed?

 

[tweeve2002]

have any fans stoped working?

Blow all the dust out of your CPU HS with a can'o'air and make sure it's still fully secured at all 4 corners.

If that doesn't help, remove and reinstall the HSF using new thermal compound.

I don't know what else to suggest.

interesting ..

i would sit at 40C idle ,.. one night, i came home and itwas at 45C. so, i left it off and in the morning, it would have a higher idle and load temp. i then took off the heatsink, blew out the dust, replaced the AS3 and turned it back on. EVERYTHING WAS the SAME. No temp changes.

oh well .. i can't be bothered to worry about my temps anymore. if it's stable and not crashing, i could careless.

it's 80F in my room and my uptime is at 19 days (i've since encoded, music in 3 formats, dvd decrypting, dvd burning, cd burning) and it sitting at 49F. oh well.

Tweeve2002: Yes... in OP. Case is a Xaser III V2000A Aluminum Series with 7 fans plus EM 460 PSU (2 fans) all working and clean. CPU fan working: 84.1CFM VANTEC (SUNON) TORNADO FAN 80 X 38 MM. And yes I wear ear plugs

Thegonagle: My next step, thanks.

Sid59: I agree ("if it ain't broke...") but the sudden spike was of concern. The SLK should keep a stock 2500+ around 39C at load.

Thanks to all.

YOu could always update your BIOS. I don't know why it would do this all of a suddent but it could be mis-reporting.

Any chance your HS might need a fresh application of thermal compound? I'm not having the same problem but I have noticed temp changes in the 10 degree range with my Abit board. One day it will show a cpu temp in the low 30's and the next day it will be in the low 40's. Room temps are about the same. It's not a problem but it is puzzling. I've finally reached the conclusion that I don't trust temp sensors.

Texun: I'm beginning to agree. It just seems that my cooling is overkill for a non-OCed 2500 and to have the temps around 50C is killing me.

When all else fails I use the old "feel it" test. Not one time when it indicated a temp in the 40's have I found the socket or HS more than slightly warmer than the board - never hot. However, I have found that some thermal interface material gets dry over time. I'm using Ceramique now but I expect some increase as summer approaches.

BTW, I am running a stock XP2800 with the SLK 800A and my temps show 37C for what ever that's worth. I agree. The 900A on a stock 2500 should be lower even with a generic fan.

Texun: Thanks again, I think a Saturday project of a complete cleaning of the SLK, plus clean wipe and re-apply of thermal stuff is my best start. I hope it's not my CPU going bad, with Vcore spikes or something.

At the risk of starting a Ceramique vs. Artic Silver battle, (I used AS III on install) I might give Ceramique a try this time.

I agree, and I'll tell ya, after using an Asus P4P800-Deluxe for 9 months, and just building a new system with an Abit IS7, I'll be sticking with Asus in the future, despite my good past experience with my Abit BH6. The HW monitors seem to be flaky as hell on the IS7. At random intervals, they'll indicate that all my fans have failed, or that one is spinning at an impossible speed (indicated in scientific notation even!), the indicated temps spike and fall at random (130 C on the CPU? I don't think so!), the PC speaker beeps and chirps at random (are these alarms?), and one time, a "bee-boo-bee-boo" siren started wailing for about 10 seconds then, before I could even open the monitor software to check, the system suddenly turned off. I immediately removed the case cover and felt the HS--it was not unusualy warm. Moments later, I hit the power button, went into setup, and checked the "PC Health." Everything looked great. WTF?

Although I know different MBs will indicate the CPU core temp differently, the P4 2.4c that used to read 28/42 (idle/running SETI) on my Asus now reads 42/65 under the same conditions. I shudder to think what my new 3.0 @ 3.3 (33/47 on Asus) would look like on the Abit.

My conclusion from this is that readings from BOTH motherboards are suspect (therefore, I trust neither to be accurate), but at least the Asus gives reliable, predictible readings, instead of flaking out at random. If my temp indications suddenly spike on my Asus, I can trust that something's not right. If they spike on the Abit. . . How can I be sure it's not just flaking out again?

If a BIOS update doesn't fix the Abit, I'm eating Newegg's restocking fee and my return shipping, and ordering another Asus. (The price was right on the Abit, but so far, it seems like it was no bargain.)

make sure something isnt jacking up cpu usage

oops forgot to mention .. i run the SLK800A and 80mm Panaflo L1A

Can you post room and case temps so we can get an idea where the cooling issue may be?

HAHA! I haven't seen fan speeds in scientific notation ye,t but I did see it spike to 137,000RPM once and thought for a second about diving for cover. :grin;

Seriously though, the NF7 that I have has been one of the best boards I've ever owned. Sorry to hear about your IS7. Lat's hope for a BIOS fix ASAP.

MyRep My guess is that when you R&R the HS and give it a good cleaning and some new paste your temps will be fine again. Since you have had a long history of good temps I wouldn't be looking at any other hardware as being the culprit just yet.

Room temp 68-70F, case temp 38C

 

[Elcs]

When I wake up in the morning and switch my pc on, it takes a while to reach a stable idle position of around 40C.... after a gaming session, load temps can be 48C ish.

When i come back from University, my idle temps seem to be around 43-44C and load temps by the end of the night can be around 52C.

I only reseated my HSF and reapplied AS5 3 weeks or so ago.

Strange occurance though.
