The colder air is reducing the high side pressure too much reducing the flow of refrigerant to the evaporator. Great for suicide screen shots but bad for heavy load. You need to either warm the room up or redirect some of the warm air from the back of the unit to the front. You should see the best capacity with an air inlet temp of around 22-27c.
Badatgames18's method is good too and may fill in gaps better if the mating surfaces aren't perfectly flat. Apply a BB size drop in the middle of the IHS and just let the clamping pressure from the evap spread it out.. no moving the evap around. The reason for that is to just let the pressure spread the TIM evenly to the high and low spots as needed.
Drewmeister actually builds these so he has better knowledge of phase than me.. when i get my ambient low i notice strange behavior also.. so to cold of a room can probably hinder the ss performance (however my ss works fine and actually a tad better @ around 13-14C vs normal room temp)
and thanks drew... i won't move the evap next time.. the first time i mounted, i just let the pressure and heat do the work without moving the evap.. was getting awesome temps... then i started trying to move the evap around before fully mounting for some reason and the spread of the TIM never looked quite right after i unmounted.Edited by badatgames18 - 11/4/11 at 10:46pm
