Temps Are Up

[dilsburger]

I have been running my current config for about 6 weeks. At first my CPU temp was generally running in the low 40's and case mid 30's Celsius so I was content and hadn't checked them until yesterday. The cpu was 55 and case 40. I hadn't been doing anything cpu or graphics intensive at the time, just some internet surfing for less than an hour and a small app install. I needed to reboot after the install so that's when I decided to check my temps since it had been awhile.

My CPU fan/heatsink is a basic Master Cooler for AMD's and the case fans are the same brand and only 2500 rpm fans but seem to be doing the job. The cpu fan is running above 4700rpm as it always has.

The case temp doesn't concern me at all but I'm wondering what could going on with the CPU temp? I believe it will heat up following a reboot but that seems a bit much. It was only a few degrees cooler an hour later idle.

The box is on the 2nd floor and with the recent heat the room temp at the time was mid-80's. I guess this could cause the small increase in the case temp but could it afffect the CPU? I'm continuing to monitor......

Should I be concerned with 55C on this cpu which I realize is a heater? Could something be failing? As always any thought's are appreciated!

It could be that dust is clogging up the heat sink. I have to clean mine out every few months. Usually when it hits the mid 50s. If not then you might want to pop off the heat sink clean everything and put on some more thermal goop.

An increase in room temperatures will absolutely cause an increase in CPU temperatures.

I suggest you get some better case fans, some with higher cfm output. Make sure to have one as intake in bottom front of case and one as exhaust in high rear of case, just under the PSU.

The temps should come back down when the room cools off, but good airflow through the case is always a good idea.

Thanks to you both.

For the last several weeks the room had been cooled by AC. That probably explains it.

Well I got it half right. My fans are exactly in those spots serving as intake and exhaust. I've never seen better fans (2500rpm) at my local puter retailer but I'm sure he can get them for me.

Thanks again!

In a hot room soom simply things can make a big difference. Get the case down on the floor where the air is cooler. Leave the door open so there's some air circulation, and a window also open if possible. Air fllor through the room is important like air flow through the case. If you can position the case on the floor, by the door, even better!

Thanks sleddog. The case is now on the floor. Tonite the room temp is down as is the case temp 33 (pretty good ?) & cpu temp 48 (not good enuf ?). Think I'll inspect heat sink/fan for dust etc and possibly replace with a better one.

Another Q for y'all - I'm using MBM 5 (Mother Board Monitor)to watch these temps. I have 3 sensors that I can monitor. 1 is case, 2 is cpu and the 3rd I can't identify becuse my BIOS doesn't show a 3rd. Yet the MBM app does find a sensor. I assigned the sensor and MBM will show temps up to 68C then drop to as low as 24 without starting a new app or anything,, it just reaches a high temp then drops

Do any of you have an idea what this sensor is ?

[sleddog]

No idea really. MBM also shows a third sensor here on my Asus board. The readout is always 0. I think it may be a provision on the motherboard for an additional external sensor that can be added? That's only a guess. If you're seeing 40+ degrees variation on that sensor within a second or two, it's definitely not monitoring anything correctly.

What does the BIOS show?

[dilsburger]

This is what puzzles me. I don't have anything in the BIOS for a 3rd temp/sensor. Only CPU and SYSTEM.....

I have no idea why mbm detects this 3rd sensor and give these readings on it. It did the same thing on the mobo I replaced which was a different chipset.

[sleddog]

As a last resort I read the MBM Help File! :)

FAQ - MBM

Q. MBM can show 3 sensors but I only get a good reading from 2 (winbond 1 and winbond 2 - P2), when I try the 3rd (winbond 3) I get nothing or some way weird number

A. You might need to buy or create a thermal sensor, which you then have to connect to your board, check your board manual for a connector, if there is on then either buy a thermal probe or create one with the help from virtualhideout, who have this site: http://www.virtualhideout.net/guides/thermistor/index.shtml

Oh my God, :eek: not the Help File! :D

Thanks for your help! Going back to my original post on this thread (and all others) - I've learned much from you guys. I had the thought that the CPU temp could not be affected by air flow or room temp... But so much to learn!:)

I was an in-house PC tech for a small company in the OLD days - DOS 3.3/IBM 8088 to Win 3.1/pentium. Then moved to mainframe programming & got away from the technical side of PC's for several years. I bought my first home system only a year ago and am getting re-aquainted with the current hardware, etc. My how the world has changed. ;) I'm having a ball after just re-building this box from the mobo up and learning nearly every day. This forum has been a blessing! Thanks again.
