My evaporator is freezing.

[Ghostav]

Hey, I just got my Mach 1 moddet with r404a gas.

Two days after, it crashed and were totally dead.

I localised the problem, my motherboard was dead R.I.P IC7-G.

I saw there was ice on the evap, some around the place where the hose goes into the evap, and some on top and under the evap.

I have mounted the kit and evaporator many times now, made sure that the seal string is sealed correctly and so on, but the same outcome every time.

It started to happen after the mod, and im so lost.

But the funny part is, that the ice is not formed around the seal string, but on the evap.

1: I start the compressor.

2: After 20-30 minutes where the compressor runs alone, it is starting to make ice on top of the evap.

3: 5 minutes later, the area around the hose is wet.

4: It get worse and worse, so i turn off the prommy.

Hope it makes sense, please help.

If fans are set to run at full at all times (which they should be) then all the Prommi's heaters that are there to prevent condensation are switched off. So you get condensation on the head and pipe. As the head gets that cold, this then freezes.

Best solution - higher overclock (therefore more heat under the evap therefore a warmer evap - ie: You aren't generating enough heatload from your CPU to warrant having a 404 modded prommi), or reinsulate the neck with thicker insulation, and cover the head's outer surfaces with dielectric grease or selfadhesive armaflex tape.

You can lower the fan speed to sort it, which will turn the heaters back on again, but if the unit isn't precisely charged that can cause complications as the highside-pressure will rise.

Other alternative.... trace the wires for all the heaters, disconnect them from the controller, and run them from a separate 12v PSU so that you can run fans at full with heaters still on.

Well, my Northwood C 2,8@4,25 ghz with 1,75 vcore should make some heat.

Me and a friend are going to solve the problem asap.

Thank you very much.
