Hi Carlos,
I have a 1000D and it seems to get more dead pixels and hot pixels the longer I use it. As Jeanette says, anything above 10 deg C makes mine come out in a rash and red blotches are all over my subs. Hence my decision to build a cooler box for the DSLR, which gives me 8-10 degrees below ambient so far.
Check it out
here for my pic using it on the weekend. My chip was reported by Backyard EOS at a stable 4 deg C for a full hour during 5 min subs at ISO 400.
32 deg C is HOT HOT HOT! What was your ambient temp at the time?
Cheers
Chris
