Thermalright SLK-700 AMD Heatsink Moving on to the fins themselves, we can see that Thermalright has taken some precaution against the accidental bending of the fins by connecting them at their outside edges. I've bent some cooling fins before and they are a pain in the you-know-what to try and get back in place.
The view from the top of the heatsink really shows how thin these fins really are. Here you also see where they connect in the middle as well. The middle portion of this cooler is in a triangular design which rises up from the base to meet the fins which also houses the socket clip. And I'm glad to see that it's the three prong jobber.
This is essentially an extenuation of the base of the sink which is already pretty durned thick as it is. Measuring only 57.5mm x 29.4mm the solid copper base 6.35mm thick. This should help with the heat transfer a great deal. The base is long and narrow for a reason. This allows air to circulate better underneath the base, keeping hot air from collecting and working against us. The bottom of the base also came with the standard sticker covering it to protect from scratches. Upon removing said sticker the base is shiny enough to use as a mirror. Definitely no lap job needed here!
The last thing we'll look at is the fan attachment. Once again Thermalright uses retaining wires to adhere the fan to the sink. Previous Thermalright sinks we have reviewed included different length clips to accommodate different fan sizes, but here they have instead used a series of three different sets of holes in the sink itself to adjust for fan size.
These wires certainly make it easier to attach and remove the fans than screws, but they just seem flimsy. They hold the fan on very well, I'm just worried that I'm gonna accidentally bend one and be unable to get it back right. But another advantage of these is that with screws you are actually blocking a small (granted, a very small) amount of the airflow in the fins. Testing Now it's time to put the screws to this thing and see what happens. We're going to see if this thing performs well enough to knock my SK-7 off the top spot on my shelf. The SK-7 will be fitted with a Thermaltake Smart Fan II running wide open (moving a whopping 75 CFM at 4800 RPMs's). Since the SLK-700 is designed to be able to handle 60, 70 and 74mm fans we're going to run this sink through the test using a 60mm and 70mm fan (sorry, I don't have a 74mm available). The 60mm fan is a Delta Black Label 7k job moving around 38 CFM and the 70mm is a Thermaltake fan rated at 49 CFM. To put the system under load we'll run SiSandra's Burn In Wizard for 30 minutes and record the CPU temps via a small thermal probe attached to the CPU. The ambient room temperature havered around 20.5 Celsius. Test System:
Standard Cursory Statement No two systems will perform identically, or for that matter, there will be variations within a single system to some degree depending on several factors. Hence our results may end up being a little better or a little worse than the results you may get in your own box.
