Proliant DL360 G5 Fanblock problem

Hi folks

I hope you can help me here:

I have a HP Proliant DL360 G5 Server, with 2 quad core CPU's. The problem is that the Fan block in the middle is running a lot slower than the others, and that results in the #2 CPU is way hotter than the other. Its runs at 29% and the two others runs at 39% according to ILO. #1 CPU is on 20 degress Celcius and #2 is on 45 degress ilde. 

I have tried looking in the Server BIOS, but i was unable to find any settings about it. 

I have also looked in ILO with no luck. I have to say, im fairly new to HP servers. 

Here is what i have tried:

1. Swapping the fan block (Problem still there)

2. Applying new thermal paste (Problem still there)

3. Updating ILO (Problem still there)

4. Updating BIOS (Problem still there)

5. Running HP Smart update tool (Problem still there)

I hope you guys can help. 

Thanks in advance :-)
