E7450 heat sink
Hi.
I've bought used E7450 at ebay and was surprised by high temperature: 80 C at built-in diagnostics test.
So I decided to change the thermal compound. When disassembled, I've noticed that heat sink doesn't cover both chips:
So I've thought that is the main problem, and bought another E7450 heat sink:
I've used fresh Arctic Cooling MX-4, which is one of the best thermal compounds ever.
Unfortunately, temperature became higher: 90 C in built-in diagnostics test.
So my main question is: which heat sink should I use?
I'm not sure if the first one is factory stock.
And second question is: can I control the fan is some way?
Thanks.

I can tell you that the original one is the correct part. This is the latest version of this heat sink not the one you bought. Dell replaced mine due to overheating issues and the new one came with a heat sink that is not touching the northbridge (second chip) and Dell said that it's the best configuration to not touch the northbridge.
Please stick with the original part.
As for controlling the fan, yes you can install "Dell Power Manager" tool from Dell site. There is a Thermal options where you can choose the cooling mode (Quiet, Best performance ..etc)

Thanks, aghanem.
You are totally right.
The only think I have to add:
original, "right" part is TW22Y (0TW22Y)
and full cover "old" one is H0WK4
