strange start temperatures

When I switch my pc off a night I also switch it off at the wall (when the mach fans have cooled down)

I mention this as I don't know if it is related.

When I switch on at the wall and wait for the restart delay to complete the evap head is reported at anywhere between 5 and -15 degrees.

Very Occasionally this means that the pc starts very quiclky (at -20) and I get a too hot error.

The evap temp when up and running looks normal - I can't comment on the cpu temp as I think my p5n-e has some issues here. It never records belwo zero even with my e6400 at stock. When overclocked to 3.8 with 1.6v speedfan can show up to 29 degrees. Seem reasonable?

The previous chip was a 3500 at 2.7 and 1.65v. this got to +3 under load, -20 at idle.

There are no signs of any leaks and the pc is stable.
 
I'd try flashing the firmware.Other than that i'd suspect a sensor is playing up.Is the pulldown time normal ?
 
no, it can be much quicker as it can start at a minus temp.

I'll try a firmware flash. I did do one when I installed this c2d system so perhaps that is the difference between this and my old system
 
ok,see how the flash goes,if it's still iffy,you have to think about a sensor, the controller or a leak.

100% agree with thickbrit here - sometimes power spikes can cause firmware corruptions (flicking a mains power switch can cause such spikes) - are you using a surge protected socket?

I sincerely hope it is firmware as my 2nd thoughts are that you have a small leak.

Normally when you get a leak,you will get the "too slow" message on the display as the unit no longer has the refrigerant capacity to pull down fast enough from cold start.As you are getting "too hot" and eratic boot delay,i'd be more inclined to believe either the firmware,a sensor or the controller were faulty.
 
ok, so after a firmware flash and not switching off all night, the evap head still reads -3 (room temp is 18 deg)

normall idle evap head temp when oc's is - 55-60

i have taken the oc off atm and it's reading -68

cpu temp in speedfan is showing +3 at idle

I think this may be down to the mobo reporting it dodgy (p5n-e sli) but I'll have a go at reseating the head in the next few days to see if that helps.
 
Bad contact would seem likely if the evap temps were not that high.

Have you checked the front of the Mach - behind the casing, could be dust blocking the radiator?

So its clear in my mind - which Mach unit have you got and the previous processor was (I assume) am AMD A64 3500? If so which one (Newcastle, Winchester or Venice)
 
Sounds like the control board is on its way out....

If that is the case its a good idea you switch it off at the wall, the other night I had the dreaded control board of death issue with my trusty unit. My system was stopping and starting after I shut the pc down I was lucky to catch it quick before it killed the compressor, even luckier for me I had a spare board in one of my other units
 
it was a 3500 winchester previously

just ran a few hours of orthos at default (1.36v)

idle 7 deg

load 8 deg

would suggest contact is ok?
 
I am assuming it's a R134 gassed Mach1 or Mach2 standard. Is that the evap temp?

To rule out anything I would suggest a reseat - or even a refit onto another system with proven cooling and temp report - or just start it up while its free standing see fi it pulls temps in a reasonable fashion.
 
i bought the unit a while back second hand as a mach 2 gt but phil confirmed from the serial that it was a std mach 2. It was suggested it had been regassed given the temps.

temps in the last post were core temps from speed fan

will do a reseat later in the week when I get chance
 
Or tell us what the BIOS says or use a different temp reporting software - maybe one supplied by the mobo manufacturer?

What does the evap temp tell you on the mach unit?
 
speedfan reports pretty much the same as bios. I also get same temps for within ati tool

atm I am at idle with no overclock

speedfan and ati tool report +5 deg.

mach unit (whichis using the 937 GT bios) says -64.

I ran this today for 9 hours on orthos and it went to +9 deg (-61 on mach)
 
Something is not right - temps on cpu are high but difference between idle and load is not that bad - mach reported temp seems off as well but also suggests R404 or R507 regas.

Weird - I guess as long as you can overlcock it cgood does it matter?

Just to confirm, all GT's are in fact factory recharged Mach II's. Not only that, but recently the capillary tubing was lengthened by a few cm to help. The controllers are different as well (albiet different firmware). So all serial numbers will point towards "standard" units.
