Getting really bad temps, help please!

First of all Iâ€™m not sure if this is in the right place, sorry.

My current setup is:
x1800xt w/ vf900)
e6400 w/ zalman 9500)
Seagate s-12 500 psu
One seagate 7200.10 and one 7200.8 hd
antec p150 case
2x 92mm nexus intake, 1x yateloon 120mm exhaust

My temps are (according to Everest) cpu idle around 50c and gpu 60c, hdds are fine with nexus blowing on them. I havenâ€™t started over clocking yet and Iâ€™m kinda afraid to with these temps. My cables are nice and neat already, and room is around 70f. I laped the heatsink and when I remove it the thermal past(as5) is spread nice and even, so I donâ€™t think contact is the problem. The cpu starts around 39 degrees and slowly rises from there, capping at 50, and Iâ€™m just baffled as to why it is so hot,other then just not having enough fan power.

Iâ€™m running the zalman controller and keeping the yate loon and zalmans at 5v, raiseing everything to 12v lowers temps by about 5 but is way to loud. I canâ€™t hear the 2 nexus fans over the 9500â€™s wine so they are still at 12v. Because I have a gigabyte ds3 and the Northbridge burns you when you touch it, I ordered a vantec stealth fan(before I realized how much they suck ï

Hello,

The reading could easily be off by a bit, and then 50C becomes low 40's -- which is fine. What are the load temps?

I find Everest can report wrong temps, try PCWizard, works for me.

yea pc wizzzard reports about 10c under everest, when what should I try keep temps at(idle/load)?

EDIT: WTF? (idle)

Processor Temperature : 32 Â°C
Processor Temperature (Core 1) : 57 Â°C
Processor Temperature (Core 2) : 56 Â°C

any ideas?

You could try turning the computer off for a while, let the CPU cool to ambient (70F), then turn it on, check temps in BIOS, wait for it to stabilise, then see what the difference is between BIOS and Windows measurements (Everest etc); also try Speedfan. Low 30's degrees C is about right for idle temp with Speedstep enabled.

Or you could get an IR thermometer.

whats speedstep?

Speedstep

Don't pay any attention to that "processor" temperature. Use the core temperatures, which can be read with Everest, Core Temp, TAT, or RMClock.

Core temps at load of 70C or under are okay. You can go lower if you don't mind fan noise...

Do you trust those programs over bios?I thought that bios is the most accurate, but I really dont know.

The BIOS reports the temperatures that the motherboard manufacturer supplies. On quite a few C2D MBs, this does not include a reliable sensor for the CPU.

For instance, on the Asus P5W DH, which is otherwise a top-of-the-line motherboard, there are ony two sensors: one on the board near the CPU socket (completely useless), and one on-chip in the south bridge (useful but misleadingly labelled "motherboard").

The on-chip digital sensors inside the Conroe are highly accurate. Unfortunately they are reported as negative numbers relative to the throttling temperature, which is a State Secret. Different programs have different ideas of this temperature, varying from 81C to 97C.

But I stand by my original advice: the core temperature reported by TAT, Core Temp, Everest, or RMClock is a much more reliable indicator of CPU temperature than that reported by the BIOS, SpeedFan, or Probe 2.

well, I assumed lapping the heatsink perfectly flat would fix any contact issues,and I didn't remount the heat sink after lapping it, and when I Did it now, I noticed that its not the heatsink, but the ihs that is convex. Does having almost all the thermal paste pushed away from the core of the processor to the sides of the ihs hurt temps enough to justify killing the warrantee?Even so I must of had a verry bad mount, because after remounting temps are down to 43 idle.

An unrelated question: Does anyone know if when you are mounting the 9500. After itâ€™s screwed in but before you turn on computer. Is it ok to rotate the heat sink a little or will that ruin the contact with the as5? I try not to, but always wind up bumping it, especially when putting the board back in the case

Thermal paste is just there to avoid having air between the chip and heatsink. If it's getting pushed out of the center, it's perfectly fine since you're getting a good metal-to-metal contact (which is better than metal -> compound -> metal).

As long as you're getting good temps, I wouldn't give it a second thought.
