Sensor Accuracy and Everest

[reidc]

Hi all-
Last Feb- I built my Retail Intel deal with the Intel 915PBL, and 3.4 gig CPU. I built it around a stock Antec Sonata(1st gen). It also has Crucial Ballistix 2x 512, and an Asus X600XT, a Maxtor 250 gig SATA, and three other 7200 rpm drives inside. I also added an additional 120mm fan inside the case. It has stock Intel cooling.

I was always worried about heat, and my fans seems to ramp up soon and often. I am getting ready to build my new Intel 945PSN with 2.8 gig Dual Core. I already have a 6600GT board for it, and my plan is to buy one new SATA 7200.9 drive plus my other SATA drive, and add a 20 Gig IDE for Linux. For a case- I am LEANING towards the P150, but am open.

Since I am concerned with heat on this unit- I now heat will be an issue with my new unit. I loaded Everest today, and my PC's been running all day mostly surfing. According to my Temps on Everest- my
Temperatures

Motherboard 39 °C (102 °F)
CPU 57 °C (135 °F)
Aux 38 °C (100 °F)
GPU 53 °C (127 °F)

GPU Memory 40 °C (104 °F)
Maxtor 6B250S0 40 °C (104 °F)
Maxtor 6Y160P0 27 °C (81 °F)

How accurate are these sensors? How are these for what I am running? Both hard drives are mounted in the sideways drive cage, and I can't believe the difference in the two(the 160 is IDE).

I had thought of going aftermarket for cooling- thinking of an SI-120. Its too late now for this machine, as my plan is to sell this one, once new one is up. Obviously if I go aftermarket for cooling- I would do that before build and power on.


Thoughts?
Thanks
Chris

compare them to temps according to the Intel Monitor

Thanks-

I would assume that all these reading(including Intel Software) take their reading from the sensor directly on the board itself- that's why I asked about the sensor accuracy.

I will install the Intel software, but I am fairly confident it'll be similar to what I have.

I just ran Intel Desktop Utilities- and got the same readings as Everest.

Before I did this though- I did a couple of things: I pushed in the pins for the heatsink and fan a bit tighter- thought I heard a click on one of them, so maybe it wasn't tight.
I also pulled my side door off, and ran without it- and my CPU was idling at 47 degrees C, with my Motherboard temp around 30 degrees C.

Once I put the door back on- my CPU temps are now 55 to 56 degrees C, and my motherboard temp is now 35 to 36 degrees C.

I also ran Stress Test(part of Intel Utilities), and within 5 secs my CPU temp was 74 degrees C, and I was getting the warning message about overheat right around 73 degrees.

My fan config is the rear 120 MM CM fan(from Antec) blowing out, and my inside Antec 120 pulling air across the drive bay and blowing toward the CPU. I really don't have a lot of IDE cables to impeed airflow either. Both chassis fans are supposedly blowing around 1100 to 1300 rpm, and my CPU fan is around 2100, and goes to 2500 if my temp goes up near 65.

If nothing else- would cleaning off my old thermal layer and laying down Arctic Silver help?

Thx
Chris

Ok- I did an upgrade!!!

CompUSA has the Zalman 9500 on sale for $60 bux. I put tht in tonight, along with some Arctic Silver 5, and I removed the fan that was behind the hard drives, as I broke the rubber mounts on the rear fan. The front fan is now on rear, and now running 1 fan only.

My Temps are down from 57C Idle to 42C, and running Prime95- I was at 75C plus last night after 10 seconds- now I can run it at 55C and just let it run.

I can believe this difference.
