    Prometeia temp, and possible short revisited?

    When I tried to hook-up my Prometeia last week the system kept shutting down, as it booted into Windows. The Prometia temperatures read -45C, but the Epox 8RDA BIOS PCHealth, and MBM-5 screen indicated (+)45C. Thinking MBM-5 DID read negative temps, I presumed it was the CPU's temp. Upon further speculation, (+)45C shouldn't be high enough to cause the types of video anomalies I was experiencing while attempting to change values in the BIOS? And then I read a Prometeia review (from here) where MBM-5 wasn't reading/displaying negative temps. It simply read -45, as 45 in that review? I tried to scroll up, and random letters and numbers typed across the screen? I placed the included shim on the CPU, however; the resistors on the CPU's surface near the core, are higher then the shim is thick. Ergo, the micro-freezer copper head, may be causing current to travel between these resistors? This is the only explanation I have for the strange video anomalies, which occured while in the BIOS.

    Has anyone ever heard of this occurring before? And would a mere (+)45C cause the types of anomalies I experienced in the BIOS. Anyway, as I'm about to reinstall the cooler, (believing inadequate contact was my problem) would adding washers to the spring-loaded mounting screws increase contact pressure, or removing them? I know it's a silly question, but for some reason I can't picture in my head what the effect will be? The manual mentions washers, but not their specific effect with regards to tightening the shi[p[if adding washers increases the micro-freezer's head upon the core? I'm about to fie the system up, and added five washers per side, however, I don't know if this is bringing the freezer-head closer to the core?

    Adding washers will INCREASE pressure on the core and is a good thing.

    However I have the same problem as you, I also cannot picture it in my head how the system works. The metal thing is pressed against the evaporator head , and no matter how many washers I add, it cannot and will not be possible to get any closer to this evaporator because it is already touching it.

    Quote from chip-con website:
    Let it settle for a while, then unscrew and unmount the coolinghead again.
    If the imprint of the core looks like on the picture here, the pressure is insufficient, and needs to be increased.

    This is done by adding more spacers to the mounting screws, just below the screw head. Currently 5 spacer rings are placed as standard, but up to 4 or 5 extra spacers may prove to be optimal on your particular Prometeia Cooling system

    Thank you Vatt, I'm still trying to figure it. It would seem to me you'd want the screws to turn deeper into the clamp. Well I set up the system this afternoon and it's just sitting there waiting to be turned on, and dammit, I just don't want to do it, because I'm afraid it won't work, and i don't want to fry my 2400.

    I did read what you reprinted for me, thank you. Did you find it was extremely difficult to align the microfreezer to the CPU clamp? I realize they attempt to make it flexible enough to accomodate either horizontal, or vertically situated Socket-A's but I had a very hard time mounting the microfreezer.

    I wrote them, and they said their using the 8RDA in their test facilities, so i assume, it's OK. BUT the clamp they provide which clamps on to the tab's on each side of the socket, seems to have a lot of play? I don't know. Seems like I'm the only person having these troubles, because I poted here, VRZone, Phase-Change, and AOA, and no one responded to my description of these difficulties?
