correct way to install a cpu cooler

[ekymetal]

Hi all
I am about to install a Arctic freezer 7 pro rev.2.
SPECS ARE

6 gig ddr3 ram corsair xms 3
intel core 2quad CPU q9550 2.83 ghz
Gigabyte mb ga-ep45t-ds3r motherboard
Gigabyte Radeon HD 4850 1GB Passive cooler
All in a sidewinder case

My question is which is the best way to install this ?
The manual says towards the ram ,there web says towards the rear .
Judging by the pics online ,first slot of ram is an issue .
I have a rear fan sucking the heat out ,and to side fans sucking in .
And intend to install a front fan in the next week or so .
Have looked at a lot of pics online ,all saying there way is the best .
Even looked at a utube video saying towards the back .
What do you all recommend ?
Also what is the best thing to clean you cpu before installing my new cooler ?
Thanks and cheers to all !

isopentyl alcohol would be the best to use to clean your cpu and heatsink before installation. and as for your heatink, test fit it with the fan towards the ram, and make sure its in a push , that way it pushes the air through the fins into the exhaust fan on the back of your case.
