PS3 PS3 Heatpipes works?

Hi,

Has anyone of you thermal pictures of the heatpipes? Is it normal that the lower 2 heatpipes runs cooler than the others?

I do not have thermal picture and to me it seems normal. First of the all the fan sits at the bottom and the cooling effect is through the heat sink. Heat rises and the fan tends to dissipate at lower level of the heat sink and as the heat rises this would be the cooler part. Meaning the system is designed to draw cool air at the bottom forces hot air out from top and back.
