So I just put together my very first build. See specs in sig. Booted up and POSTed on the first try, flashed the BIOS no problem and got Windows installed real fast.

Then I decided to do some baselines, downloaded cpu-z, hwmonitor, and core-temp 0.96.1.

I'm running about 37-39C idle and 49C on a quick Prime95 run. Does this seem a little warm? I tried to lap my freezer pro 7 as best I could, but that damn thing is so hard to lap because of the pin location. I'm using MX-2 Thermal paste... pretty sure I did everything right there.

It's running at 1.184 vcore.

Anyone else seeing temp issues?

So let me get this straight? On your first build you tried to lap stuff? Well I will give you a small tip that might save your problems. To see if you even need to lap you take a clean razor blade that goes in a utility knife and you lay that edge side down across the cpu heat sink and then over the heatsink fan that goes on top of the cpu. That way you can determine if it even needs to be lapped. There is always going to be a small amount of concave or convex area, more on the cpu factory heatsink than the aftermarket heatsink fan. To clarify, CPU heatsink is the gray metal casing on the top of your cpu core. Not the heatsink fan that comes in the retail box. Cores are so small these days that the makers decided to put their own casing over the cores. You may have actually harmed thermal transfer by your lapping attempt, you really shouldn't try that till you are a bit more experienced. What you need to try to do is follow all directions on thermal paste. I would clean both the Heatsink and the cpu and redo your install. Make sure that it is screwed on tight enough. The temps do seem a little high but that is first gen 45 nm so they very well might be that hot.

I did the razorblade test to see if it needed lapping, it was pretty bad. The little lapping I did, I did see a slight improvement with the razor blade test, but with the freezer pro 7, the way it is designed, it is really hard to lap. I left the cpu alone.

As far as experience is concerned, this is my first ground up build. I've been working with hardware for 18 years, just never got around to building my own machine. Can't get good at lapping til you try it, eh?

I had problems with my freezer also. Tossed it and dropped in stock. Problem solved.

im on the freezer pro 7, slightly lapped b/c it is hella rough to begin with-- with some as5, 8400 oc'd to 4ghz- 37c at idle, 53@ load. tested with orthos @ 3hr. measured with latest core temp. Using asus p5k board.

Question though- no matter what I do to turn speedstep off--it stays on. (i flip the disabled swtich on bios, boot back up and its on again-- it is weird)
This has my voltages all crazy b/c at idle the cpu is at 1.3 volts (not worried about overvolting as the max on this proc i believe is 1.36) but at load this proc drops to 1.248. is this normal???

I dont really mind b/c it is rock stable and the speedstep allows the proc to stay really cool during the majority of my work on this comp (non gaming) but when it needs the power it scales up to 4ghz in a split second. not bad.

There are probably other attributes in the BIOS that need to be disabled to turn off the speedstep action you're seeing. I've got the Gigabyte ga p35 ds3l and I had about 3 or 4 switches I had to turn off to get it to stay at 3GHz for the entire time I had it up and running.
