Best cooler for duals and quads?

Why oh why is it 160mm high (infinity), my lc17 case can only fit upto 140mm high

I think the SL-128 4-heat pipe design, even though the pipes are much "thicker" than regular ones, is inferior to 6 or even 8 heat pipes. It's definitely not a matter of the surface, because it appears to me the SL-128 has even a slightly bigger surface than the Big Typhoon.

Awesome .. yeah I really like how my Scythe Infinity performs definitely one of the best air coolers I've used to date

I read across alot of forums the SI-128 is just a revised SI-120 and doesn't bring much performance improvements at all, even the the Thermalright Ultra 120 http://www.pccasegear.com.au/prod4119.htm is alot better than the SI-128 and slightly cheaper.

time to mod your case, cut a square hole at the top and do a car/hotrod like mod hehe

An air scoop would look cool

Looks like you've outgrown your case. Time to get rid of it and not use one.

Stop it you lot, its supposed to be an HTPC, do I have to cut holes in every case I have ever owned

- Quad Core QX6700 2.66@3500 Mhz
- vcore 1.4 volt
- PCB mounted on open tray
- Ambiente around 24C
- all 4 cores running at full load (folding)

Infinity: 65C
BT: 69C
SL-128: 78C

Hope you dont mind if I have linked this post quoting your name

there's a 140mm fan + 120mm adapter on pccasegear.. that'd have some kick surely?

after reading about the 160mm fan cooling the PS3 it got me thinking about how high we could feasibly go with fan sizes

i havent been following the whole thread but i gather chainbolt that you dont stand by your earlier assertions that a HSF should follow intel's recommendations and blow down onto the motherboard to cool mosfets and VRMS as well? Just that you know are saying the scythe infinity is the go, when it actually blows across the board if im not mistaken?

with scythe infinity if you position the fan on the heatsink a tad lower you can also cool the components around the cpu socket too as most reviews have the fan mounted higher up which doesn't provide any air flow around cpu socket area

Chainy's 4C diff between Scythe Infinity and Big Typhoon agree with my results as well

That is exactly what I do. Keeping the sink above the socket also in the air stream gives you another 1~2 C when you use a powerful fan.

In addtion: throw away this weakling of default fan, and use a grown-up 120x35 fan. The springs have to be modified for this, you need flat pliers for this, but no problem.

Have a read of this excellent article, plus photos at site:

Since I already had in hand a Scythe Ninja heat sink and matching duct from my previous build, I switched to that heat sink, which I knew for certain could cool the CPU quietly. The Ninja is huge and efficient.

While running the CPU at high voltage, I noticed that the VRM was getting pretty warm, though not nearly as hot as on my old motherboard. Still, it was hot enough that the heat pipe to the north bridge was actually working backwards: it was transmitting heat toward the north bridge instead of away from it.

My stockpile of earlier experiments contained a Thermalright HR-05 tower north bridge heat sink, so I decided to try it instead of the stock heatsink/heatpipe/radiator thingie. This was not particularly easy because although the HR-05 comes with a clip designed for Intel-style hoops, it is designed for hoops on the northeast and southwest sides of the north bridge. For some bizarre reason, the P5W DH has provision for all four hoops but only has two of them populated: the northwest and southeast ones. Mounting the HR-05 required severe bending of the clip to reverse the angles, since I didn't want to take a soldering iron to this insanely expensive and hard-to-get motherboard.

When mounted as designed, the HR-05 can be rotated to various angles as needed. In my reversed orientation, the attachment clip bumped into the bottom fins, and prevented this rotation. To address this, I cut notches in the bottom two fins.

The HR-05, though billed as a passive heat sink, does need some airflow to cool an overclocked 975X. Also, since the Ninja is a tower heat sink, there is no downward airflow onto the VRM from its fan. Fortunately, the fan on the Ninja can be positioned so that it pushes some air between the Ninja and the motherboard, and also between the Ninja and the HR-05. To capture as much of this air as possible, I angled the HR-05 with respect to the Ninja.

has anyone tried out the ASUS silent square??

Q: Do you people with High RPM 120mm fans wear ear plugs? I assume its punching out 75db+. Wouldnt prolong exposure to that be harmful to your ears?

or our old friend the zip tie

They cannot hear your question, you will need to SHOUT
