After buying a good heatsink, what is the single best thing you can do to cool your cpu and overall temperatures?

Make sure you have good airflow in your case. Thats about it.

Keep the heatsink and fan clean.

Yes, definitely pay attention to airflow. Bundle cables using zip ties and add a decent exhaust fan. If you can, make sure the CFM for any fans blowing air out of the back of your PC is greater than the CFM of fans sucking air into it.

VYup, just make sure its seated properly and you have the right amount of thermal compound.

Another tip, if you have a heatsink which has a fan perpendicular to the motherboard, match the direction of air flow with your rear case fan. That way you are pulling (or pushing) air thuroughly in/out of the case.

Does anyone know how to control your fan speeds through software? Or can you only control it manually? I want to be able to plug my case fans into the motherboard but they only have the molex ends. Can you only control your cpu fan?

helium freezes at 0.95k, below -270°C, try sticking some of that on there.

You can use MOLEX to 3PIN converter and these 3 PIN converters can then plug into 3 Pin headers in the motherboard. But be careful that the case fan's ampere rating does not exceed the motherboard's 3PIN header ampere rating.

1. Start w/ a good case.

2. Avoid gimmicky coolers that block case fans exhaust.

3. Use a Heat Sink and TIM that near the tops of the list.

pick a TIM from the top few here:

4. Understand the realities and myths of lapping, air flow direction TIM application. For example:

5. Be neat with cables ..... sleeving multiples cables in a common sleeve is a good way to reduce clutter.

6. Keep heat sinks, fans and components free of dust.

7. Dump Molex connectors....snip, snip....yes you can use adapters but their bulk results in a a bundle of flow blockage. I either unsnap the molex connectors off or snip them off when I am stuck with them and solder on new 3/4 pin connectors. Better yet, buy case fans with 3 pin connectors. Enthusiast MoBos typically have fan headers rated at 2 amps while most case fans draw about a third of an amp. Provided you have checked your ratings and left some headroom, you can gang common fans (i.e. twin rear case exhaust////twin case from intake) on a single header.

8. To control fans via MoBo, you'll need a MoBo that provides the feature....not all do.

9. If you have connector issues , lack of MoBo features, or whatever, you can always use one of these:

hey Jack,

my motherboard is a p6x58d premium, and my case is an antec 300 illusion. Can you take a look for me and see what you would recommend I do with my fan/cooling situation?

open your casing and dont put ur case in a corner

Actually, on most mid to high end cases leaving them open will impede the the proper flow of air across the M/B CPU area.

Make sure all input fans have filters and keep them clean.
