Temps, something wrong?

*** ed up or something, dont allow me to changed FSB)
its with Kandalf LCS case (thermaltake water cooling).

According to the thermometer in my room, my ambient is right now 26C, but im quite sure its like 22 cus at 26 i feel its "HOT".
Now the problem is that my thermal probe in water says the water in my loop is at 27.0 C, and Core temp and Real Temp record minimums on IDLE at 26 C.

Should i not trust the temps from the software, from the hardware recording the water temp, or none at all?.

thx man
