I've been having a bit of trouble keeping the old CPU temperatures down recently so I ordered one of these and I wanted some advice on airflow.

On an intel based motherboard this fan would be next to the RAM and blowing air out the back of the computer, however this is an ASUS motherboard so the fan will be on the bottom and blowing air upward toward the PSU and top mounted case fan (exhaust).

It only occurred to me after ordering it but there's a fan on the side of my case blowing air into the computer, it's also located directly in front of where the heat sink is, which is great for standard fan but I'm not sure how it would affect the airflow around this type of heat sink, it'll basically be blowing side on to the fan.

I have a habit of being paranoid over nothing so maybe it'll be fine, I'd still like some advice though, if you have any to offer.

You say it is recent development. Then remove old heat sink, remove old thermal compound, apply new thermal compound, resit the heat sink.

The fan has slowed down quite a bit too. Plus it was never really "cool" to begin with, it was the stock heat sink and fan though.

remove dust from heatsink?

I have my fair share of empty air duster cans.

Unless youre overclocking not going to be a huge issue. You'll only run into problems if you have the airflow going in opposite directions (Cool air in v. hot air out) so make sure everything is going in a uniform direction from front to back etc.

If you're referring to a fan on a lateral part of a case blowing perpendicular to the fan then no it's not a large issue. I assume it's an 80mm?

But really so long as youre not overclocking or getting heat warnings it's not going to be an issue.

Hm, you should check on the temp readings, between optimized use and heavy load. If its too hot, followmsaid advice on new paste and resitting heatsink.

While on subject, thinking on getting one of them 60-70 bux watercooler. Should I consider getting for my aging q6600? Thinking to overclock to around 3ghz or maybe 3.2. Taking good care of my first built sysyem and stilll got good enough life for next two or three years. (built the new pc when 8800gt gpus cam out a few months later, its old!)

It's December... whip the side off the case and put it in the window Big smile The sub zero temps outside should keep you running cool until around May (if in the u.k) P

I have run Q6600 at 3 GHz on air cooling before, no need for water cooling for that. If I remember right, the fastest and stable that I got from mine was 3.1 or 3.2 GHz, air cooled.

My heat sink is Rosewill Z5: http://www.tweaktown.com/reviews/1232/rosewill_rcx_z5_cpu_cooler/index3.html I got it as part of combo when buying cpu from newegg, way way back.

Hehe, it's not near the window but I have been leaving the window open, makes a huge difference. Luckily I don't really mind the cold.

This one had an 8800 in it, and that was a replacement after the first card burnt out. It might be as old as yours.

Do you need to overclock it?

Had a friend do that actually got the worlds fastest O.C time for a specific AMD processor and Mobo...Then a few minutes later it exploded. But he did manage to record it! b

Believe it was -15 F when he did it... So roughly what -26C?

I used to keep the window in my office room area at my old apartment open in the winter slightly, lol. It was usually like 50 or 60 degrees in there.

get the air flowing a bit like in this picture http://www.theschierers.net/blog/wp-content/uploads/2009/07/case_airflow.jpg
you want cool air being drawn in from the front and bottom and being vented out the top and back. have the fans on your CPU cooler running to keep with that flow so either blowing up or back.
if you have a fan on the door of the case have that blowing in on top of your motherboard.
always have more fans blowing in than out. you want a positive pressure in your case so it keeps more dust out of your case. if you have equal you end up with air going everywhere and if you have negative airflow (more fans pulling out than putting in) you end up with tons of dust in the case.
as to your CPU being too hot. make sure you cleaned both the CPU and the contact plate on the cooler quite well before applying new thermal paste. and when you do apply the thermal paste, put a small bead of it on then spread it with your finger. spread it like it were butter or jam on toast, don't have large clumps in one area and leave another area deprived or clear, and try and get it as even across the surface as possible. once you've done this the heatsink should just drop on and work fine.

Heatsink came today, waaaaaay too big. I knew it was big but I never expected it to overlap my RAM.

I have a fans on the side and top of the case but nothing at the front, how would I handle positive air pressure? I could have top and rear as exhaust but that would only leave the side fan (right in the middle of the panel) for intake.

As to the othe.. huh!? Spread thermal compound with my finger you say? *backs away slowly*

Use plastic knife to scrap off old thermal compound.

Squeeze some new thermal compound in the middle of the cpu, about the size of the rice grain. Install heat sink.

Done.

Doesn't matter, I used water and some dish soap to get it off then gave it a bit of a wipe with some light oil.
