Testing for these sinks followed my normal guidelines so that I can have results that are fairly compared to other heatsinks without bias. Ambient temperature during testing was 21-22C, voltage was set to 1.80 volts and the test system consisted of:
Antec SX1030 Tower Case
AMD Thunderbird 1000 (AVIA)
Abit KT7A-RAID Motherboard
256MB Crucial PC133 CAS2 SDRAM
Arctic Silver II Thermal Compound
Prolink XX-Player GeForce3
Since most of the heatsinks coming out are designed for higher spec systems, I have forgone the 1000MHz and 1100MHz tests. This will allow us to concentrate on whether or not the new sinks coming out can perform up to today's standard levels. After all, with the budget systems coming in at 1.2GHz and higher, it's time to set the mark just a bit higher in our heatsink comparisons.
Testing itself included measuring the temperature at idle, after a Quake III Deathmatch battle, and again after a continuous looping of MadOnion's 3dMark2001 Demo. These are the same testing criteria that I have been using in the past, so am maintaining some consistency for the sake of comparison.
So how did the Evercool products manage to handle the heat of a 1000MHz Thunderbird that has been overclocked to 1333MHz? Only one way to find out
I added the Alpha PAL8045 above as a comparison. Granted, the Alpha unit is a very high-end heatsink, but by including it we can see just how well the Evercool units compare to the competition. After all, if we are going to spend out money, we may as well see what we're getting, right?
Results ended up being pretty much where I figured they would be. The ND12 series cooler pulled off middle of the road temperatures due to its aluminum construction and decent fan. While it doesn't blow away the other models out there, it produced a very acceptable result. Likewise, the CUB series cooler also put up some good numbers. The copper sinks almost always win out in the end because they are just so much better at conducting the heat upwards so that the fan can get rid of it.
I was surprised at the results of the CUC model. With the very small fan and aluminum material used, I had really expected to see higher results. It is common practice to shoot for a temperature range under 50C, and even with the tiny (and quiet) 19-CFM fan, it managed to meet that goal. Remember also that these tests were conducted at a 33% overclock, so heat output is in the vicinity of 73.6 watts. Very nice results for a smallish HSF.
What we have here is a group of heatsinks by a manufacturer that is trying to make a new name for itself. While the Evercool line won't take the crown for coolest heatsinks on the market, they will allow you to have some efficient cooling capabilities without creating a huge gap in your wallet. To give an idea as to pricing on these units, consider that the ND12 model goes for US$10, the CUC goes for US$15 and the CUB model sells for US$19. These prices are very acceptable for the cooling you get.
Something else to consider is that none of these fans will emit the kind of noise that is common with the Monster Delta models out there. While I can't say enough about the cooling prowess of these loud units, the less noisome fans made for a pleasant change of pace.
Bottom line...Looking at the performance vs. dollar aspect, any of these coolers will fit the bill for those who are wanting some good cooling for a decent price. I wouldn't recommend going much higher in speed for the CUC unit, but the others will suit your needs for nearly any of the current crop of AMD processors on the market.
