Need help with Temps!!

[mcala]

I have read the Temp sticky on C2D but i still can't make out if these temps are accurate.
This is from Speedfan:
Temp1:36C
Temp2:20C
Temp3:-2C
HD0:35C
Core0:15
Core1:15

This is from TAT:
Digital Temp cpu 0
17C
Digital Temp cpu1
16C

And finally my temps from the Gigabyte Easytune5 motherboard software:
System 36
CPU 21

I have the Zalman 9700 HSF ,1 120mm rear fan ,1 80mm front ,1 80mm side fan & 1 120 mm on the powersupply.
My house temp(ambient) is a 75-78 Fahrenheit constant,i live in hot *** Florida so my A/C runs non stop.
I have read the Temp sticky twice but it didn't help me find a true CPU temp.Just let me know if i'm pretty safe here.I do have a mild OC but stock voltages are being used.

I don`t think they are correct. Come on 15C for the CPU... with an air cooler. Try updating the bios.

I am running the latest bios already.Forgot to mention that it's an E6750 on a Gigabyte p35-ds3r
