Circular grooves on the base of my Ultima-90.. worrysome?

[quadraphonic]

I've got just about all of my components and am gearing up for a build this weekend. On inspection of my Ultima-90, I noticed circular grooves on the surface of the base. Obviously, they're part of the machining process, but I'm wondering if you guys can take a look at some photos I took and tell me if I need to lap the HS, or if it should be good to go. Any help would be greatly appreciated as mounting the HS is the part of the build I'm most worried about.

Ignore the dust! I've got some Arctic Silver ArtiClean to spruce that baby up.

the circular grooves, to me, don't seem to be the problem. However you do have some sort of gash/blotch mark in the middle that i would check out.

I think it was residue / remnants from machining. I wiped it a bit with a lint-free cloth and it cleared most o it away. I imagine the ArctiClean will take care of the rest. You figure it's good to go?

usually a metal piece like that will be "fly-cut",
just a machining term for a bit that holds one
or more carbide or similarly hard bits.

the cutter - that cuts the metal flat - rotates
at about 2400 rpm while advancing at a speed
of approx. 1 inch per second. 2400 rpm =
40 revolutions per second, which would yield
40 grooves per second, at that feed speed.

nothing to be worried about. just a sign of
normal metal machining technology.

Right on.. I'm out to pick up a PSU and will get on the install later today. Thanks for your help guys!

I just picked up my own Ultima-90 -- after months of commenting on it here in the forums based on several reviews and "look-sees" of the engineering drawings and other resources.

They STILL have deliberately machined the heatsink base with a convex ridge, but the convexity is shallower by 0.5 mm -- half the amount of the controversial U-120-Extreme heatsink base. I SAY -- "LAP THAT SUCKER." It looks like even less work than such would be the case for the Ultra-120-Extreme.

It's going to be a month until I can get that project going, but no worry about parts or plans.

It's just a part of the machining process. It won't effect cooling very much.

FWIW.. I got everything together. No mobo beeps (thank god) and everything seems to be running well. I'm still trying to figure out Speedfan / Coretemp (I've also got issues with running Coretemp in Vista with it's driver validation) to know if my temps are reading right.. this is what I get from Speedfan.. seem ok?

Temp1: 44C
Temp2: 30C
Temp3: -2C
Temp: 0C
Core 0: 21C
Core 1: 20C

If those are speedfan temps then add 15C to your temps and that is correct. Core temp will get the temps of the digital diode inside of the chip to get you an accurate "core temp".

This Core Temp hack for Vista 64 works. Link With this hack you have to run a .bat file and then Core Temp.exe every time you start CoreTemp. I modified the .bat file so it it runs Core Temp.
First create a folder, i.e., CoreTemp, then unzip the 4 files in the hack to this folder. Right click on the coretemp-startup.bat file and edit.
Atsiv -u ALSysIO64.sys
Atsiv -f ALSysIO64.sys

Add a start command that will load Core Temp. Change the path to where Core Temp.exe is located. My file looks like this:

Atsiv -u ALSysIO64.sys
Atsiv -f ALSysIO64.sys
start "CoreTemp" "C:\CoreTemp\Core Temp.exe"

Save the file and create a shortcut to the .bat file on your desktop.

Core temp and Speedfan show the same temps on my E6400.

That's great.. thanks a bunch! I'll get that set up later today.
