Severe overheating issues

Hey guys, i'm having this really bad overheating problem and i'm seeking a few different opinions on what i need to do to fix this problem.

I'm running a i7 920 processor on 2.66 GhZ.

Lately my computer has been reaching extreme heats, i've had it since 2009 and haven't encounted such bad overheating until now for a few months, its at the point where it shuts itself down to protect itsself during big renders such as sony vegas or cinema 4d.

Right now under no heavy load (few chrome windows skype messaenger and stuff) i'm rocking a healthy 95 degrees celcius on my CPU and between 97-100 degrees on each core.

I have 5 fans (2 mounted to back one on processor power supply and graphics card)

Heres a picture of all temps/voltages and stuff like that if its of help

I also managed to pass the intel diagnostics test somehow with 1 degree under maximum, and thats where it sits, even in idle, at around 95 degrees.

I've had a few opinions so far, computer shop says new CPU and motherboard. Intel says it could be the board or the fan/heat sink in the processor.

seeking some opinions on this as overheating is getting severly bad. Thanks in advance!
