A very important thing I must make you aware of is that you do not need the additional heatsink and CPU fan and if you did use it you would void your CPU warranty both AMD and Intel are clear on this, see below;AMD;
This Limited Warranty shall be null and void if the AMD microprocessor which is the subject of this Limited Warranty is used with any heatsink/fan other than the one provided herewith.

Give the stock HS and fan a chance and if it is no good or noisy complain to Intel and put the ball in their court.
