fan position/cooling question i5 2500k overclock

I am recently looking into over clocking and have noticed that my cpu fan may not be pointing in the ideal direction. Its pointing straight into the top exhaust fan on my case, so am i right in thinking this is causing a negative air intake to a degree?

I am thinking of turning the cpu heating around to face the front or down!

Is this a good idea, will i see better temps and if i do this, do i need to clean off and reapply thermal paste?

Thanks

What case and cooler are you using?

Majority of cases you have the warm air from the cpu being extracted out with the rear case fan and draws cool air from the front intake fan.
 
I have an antec one hundred, it have a big fan at the back and top to take air our but my cpu cooler, artic freezer 7 is pointing right at the top fan so i was wondering if i should turn it so its facing the front where cold air is coming in from?

I believe that is the correct orientation of the Arctic Freezer, the fan drags the cold air from the front through the heatsink with the exhaust also dragging that air from the heatsink.
 
If you have a n exhaust on the top of the case, than having the CPU fan pointing upwards is absolutely fine, and in some cases better performing than having it pointing toward the rear of the case.

In other words, its completely up to you since you have both a top and rear exhaust fan, so either orientation will work fine.
 
You will need to move the cooler around, as at the moment I think you mentioned the top is an exhaust your cooler fan and top will be fighting each other. The cooler draws air through the fan and out.

yea this is what i have been wondering! so do you think changing this willl result in better temps? as you say currently they are pulling air away from eachother

Yep, it will be worth a shot and re apply fresh paste as well and give it a quick dust :)
 
have just changed the CPU cooler for a coolmaster hyper 212 evo, facing the right way. before the change at stock i was getting up to 60c in bf4 and am now getting 44 max :) so thats not a bad improvement i think i should be able to overclock the i5 safely now

do i need to let it settle in first? i just used the thermal cool master compound that came with the cooler. i remember with artic i had to let it settle in for like 200hrs?

Nice drop in temps.
I would give it a couple days, but most of the seating is done in a couple of heating and cooling cycles.
Old cooler was probably getting pretty dirty. I usually brush / blow mine out a couple times a year and wash them every couple of years. And that's with all intakes filtered .. which need cleaning every couple of weeks.

i shall keep this in mind of this cooler then, try and clean it out a few times a year. i got a bit excited before seeing your post and have upped my clocks to 4.5ghz and am now stress testing! was hitting 90C before but so far its sitting at 60 tops in prime

i do have a few more questions though. should my CPU fan be set to full on or auto? its currently set to full on i believe.

if this overclock goes well, should i be using fixed voltage (currently 1.35V for this) or offset?

and i also manually set my RAM settings. by default on auto they were set to the wrong MHZ, 1033(or something like that) when infact the ram is 1600mhz, so i have set that manually it to 1600mhz with the timings 9,9,9,24 at 1.65 volts. do i need to monitor this too? if so how?


thanks

(after 1 hour of prime95, 4.5 1.35v)
