Are these any good for a CPU cooler: Akasa Piranha HP Air Ripper??? - Page 2

post #11 of 12
If you're looking to not only replace the fan, but improve performance at the same time, I would consider ssomething likea San Ace H1011 120x38mm fan or any oother120x38mm fan (KKoolance 120x38mm 2600rpm 117cfm 6.4mmH2O for $9, but not PWM). Combine the fan with a shroud, anything from the Phobya 120x7mm shrouds/decouplers to the various 25mm+ shrouds, with the fan in push.
Then, remove the rear case fan grill and replace it with a simple wire grill to allow the air to flow freely out of the case.

Of course, the cooler itself will become a limiting factor, but you can maximize it's available performance and still see a temp drop as a result of more efficient heat conduction (transfer) and dissipation.
Use a top-notch thermal interface material, I prefer Prolimatech PK1, IC Diamond, and Antec Formula 7 (in a pinch), although the new PK3 is supposed to be a solid improvement over PK1 (which is already one of the best performing TIM's available).
You can try lapping, but I haven't found it to be worth the effort with recent processor families, giving maybe 1-2C; I remember lapping my FX-51 and the heatsink I was using at the time and seeing as much as a 10C drop...
Instead, I would recommend trying the "tinting" method of TIM application, which is essentially using the TIM to polish both the IHS and HSF contact surface, smoothing them out a bit but more importantly it causes some of the tiny metallic particles in suspension to "fill in" a lot of the tiny surface imperfections. This means that you end up using as close to the minimum amount of paste possible, which allows for much more true metal on metal contact, greatly enhancing the transfer efficiency of the IHS-HSF contact. It takes a bit of practice to get it perfect, but I have seen consistent drops in temps of 4-8C over the "traditional" application methods, such as the (poorly named) "grain of rice" (should be the size of a BB, grain of rice is too much), the "X method", or the "line" method.

The H212 coolers, being HDT designs, do require a bit more paste than most as a result of their comparatively uneven contact surface, but the ideal way to compensate for this is by filling the gaps with the TIM (and then using a straight edge to remove excess) prior to applying the BB size drop on the IHS for mounting.

In summary:
- 120x38mm Fan (San Ace H1011, Koolance 2600rpm, etc)
- Shroud between fan and HSF (Phobya 120x7mm or 120x20mm, or others)
- Better TIM
- Improve efficiency by improving contact (tinting, etc)
- Free Exhaust Airflow Path (remove rear case grill, replacing with a wire grill, decreasing resistance from 50-60% to just 3-6%)

- Eventually get a better cooler (ThermalRight Silver Arrow SNB-E Extreme, Phanteks tower coolers, or if you want to get better cooling on a budget, the Deepcool Assassin or older ThermalRight designs)


Hope that some of this is helpful!

the CM Bladmaster fans are actually very good. i hear they are better than the Xtra Flow fans that come with the Evo. Swiftech Helix fans are good also. i have a few of them.
