hello.
If the front case fans you have are not very good, these will make a huge differnece in case temps. Scythe Slip Stream Kaze Jyuni 120MM Fan 1900RPM 110.3CFM 37DBA
Put them back to back wherever you can. Oh, they are a bit noisey at high RPM(quieter then most), but air cooling comes with noise wether you like it, or not.
or its may be the solution
Ask your motherboard tech support where the sensor (it should be listed in the bios) exactly is on the motherboard and what it is susposed to be measuing before anyone gets too alarmed over any temps.
Also the sensor monitoring chips used on the motherboard sometimes have more sensor "ports" that installed sensors. Many times "temp programs" will read that unused port and give wildly "insane" readings etc.
On newly released motherboards expect later bios releases to "adjust" sensor reporting code so that in the bios the temp can change by large amounts from bios to bios as the manufacturer tries to improve the accuracy, (or reduce support calls from users).
