Strange goings ons with an abit KT7A raid

[AnthonyM]

My roomate has a KT7A-Raid board (I have a plain KT7A) he's running a tbird 1133 at 1400, no prob right? well one little wierd thing.... his tempatures never seem to make sense... for example, from a fresh reboot his chip is 90F, lets say he then starts seti and his temp goes upto 123F... after shutting off seti his tempature CLIMBS to about 126F and STAYES there, never goes down unless he reboots... here's the kicker... if he starts seti back up his tempature goes back down to 123F, has anyone seen this kinda of odd behavor before? (temps are not static, depends on room tempature, etc) also not just seti causes this behavior, anything that creates a load will cause this strange behavior
