wow... i can't believe that Xigmatek wins...
what fan did u use in this test?

why do ppl suprise at the Xigmatek's performance?

issit because it's no as expensive as TRUE?

The Xigmatek is good... I just hate pushpins

yes. i thought more expensive TR120 eXtreme was going to win.

The price for this 3 heatsinks?

Please apply the thermal paste evenly cause the thermal paste will affect the result too. For the pic u can see the Xigmatech have more even thermal paste surface than the other

and this r some results i get from web.

IMHO this test is too simple. If you refer to a proper test like the ones they do on Anandtech, they not only test the coolers' performance at idle and load, but also how high each cooler is able to overclock, i.e., the cooling ceiling of each cooler. For example, they tested the CM Hyper 212 and found it to be very close to TR-120EX at lower overclocks, but once you go higher the Hyper 212 will saturate faster, meaning at a certain point it will not be able to cool any more, while the TR continues further.

Another thing to consider, some reviews have pointed to the Xigmatek being noisier than others, especially when the fans are maxed out (which they needed to do in order to release the full potential of the 1283). TS should have tested both min and max fan speeds. The Noctua and TR-120EX have more fins and are deeper, thus needing higher airflow but are designed such that noise is minimised.

That said, at the current settings for this test, and assuming one doesn't need to OC higher, the Xigmatek in this review does indeed seem to be performing really well.

Wah, abang honda city modded so active in forum now.
So free now ah?

No more spending time on your car leh?

i find wat u say true bout the cm hyper 212... when i pump high voltage, high overclocks, the cm hyper has a tendency to wane away.. maybe due to the structure of the cooler itself.

I wonder if orientation of the HSFs affect performance for multi core-processors, as some are direct heatpipe contact with the processor heatspreader. In some configurations the heatpipes may actually rest over a larger area of the core's immediate heat dissipation through the heat spreader in multi core processors than others.

say, i mount my tuniq tower vertically(in casing), will it have difference performance compared to horizontal mounting? coz the pressure from horizontal is much better

Haha! Just like you retired from OCing, I retire from car modding loh Spend more time modding pc plak

Added on March 23, 2008, 6:03 amIINM I've read somewhere that for processors with integrated heat spreaders like the Core series, the most important part is the middle where the cores come in contact with the heat spreader. So it's best to mount in a way that all three direct heatpipes get in contact with the HS. Mounting it the other way, where only one heatpipe is in full contact while the others aren't, means that only the middle heatpipe is doing most of the work

However, you also need to consider the orientation of your heatsink in relation to airflow. No point having the best contact if that means having to position the fins in contra-flow of your casing's ventilation

Added on March 23, 2008, 6:18 amFrom what I gather, the number and size/length of heatpipes play a crucial role in determining how much, and how fast the heatsink is able to transport heat away from the proc. By adding two additional heatpipes to the original TR-120 improved the performance of the Extreme by a fair bit.

The next important piece of the puzzle is in the number of fins it has, to dissipate the heat from the pipes. How the fins are designed and placed, will determine the type of fan required in terms of CFM and static pressure. Fin design also affects noise levels.

Some fans may have high CFM in free-to-air situations (no restrictions), but place it in front of a restriction like a radiator or heat sink fins and it will not perform as well. Case in point are the Silverstones. The FM-121 has higher CFM than the FM-123, but the latter has a better static pressure rating so it's better to use the FM-123 for heat sink or radiator applications while the former is better for case ventilation.

As for the Hyper 212, have you tried to attach another fan? That heat sink is well known to perform much better with 2 fans. It even comes with all the necessary attachments for a 2nd fan

yeah i did, and its awesome.. i mean for what you pay for, its definitely the best bang for the buck, just for an addition of an extra fan..
