With all the new dual core and quad core processors in the market now a days using more and more power and producing more and more heat, many people need to upgrade their cooling, as well. For many, stock coolers work just fine, but what if you have a water-cooling system?
I`ve been running the Danger Den (DD) kit for a few years, and they have never left me behind. I love my old TDX block, but now the guys at DD have come up with something new: the Danger Den MC-TDX, which is specifically made for quad-core processors. I have yet to find out what the “MC” means in the MC-TDX means but I figure it stands for “Multi Core”.
Looking at the block’s features, I see that is has an Anti-Tarnish coating, but does it work and why is it needed? If you’ve messed around with water-cooling for long enough, then you’ll notice that copper corrodes, and can leave nice fingerprints on its surface. If you want to test this, then get out a piece of copper and scrub it so there is no oil or anything protecting the surface, then wet your thumb and press down.
Leave that thumbprint there for a day and you can see the results of your skin’s oil on the copper. You can renew the copper with a little metal polish, though. Since I had to run some new tests on the old TDX, I decided to perform this scrub-down to verify the coating’s claims. A quick wipe of my sweater sleeve removed the smidge, leaving no corroding fingerprint.
The base of the block is lapped and polished to a flat mirror finish, and doesn’t show any machining marks we usually see (even in high-quality parts). Danger Den uses their Lucite top, but it’s also available with a brass top for an additional eight dollars.
I didn’t count to verify that there were 240 columns in the block, but it looks about right :P. I’m surprised that DD would use columns now instead of complicated notches (as in the first TDX) for optimal water turbulence. Other companies are starting to use columns, as in the Gigabyte water-colling set reviewed here, which ended up being a great performer.
Before testing I cleaned the CPU and the MC-TDX with some Akasa TIM-Clean. Arctic Silver Ceramique thermal compound was applied between the CPU and the block and allowed to set/burn in for a few days before testing.
To be honest, I didn’t think that the old TDX design could be improved upon, as it was rock-solid and has proven to have outstanding cooling properties. Let’s see if this new block can make my dual-core processor more “cool” than it already is.
The test rig used consists of an Asus P5W DH Deluxe with a Intel Core2 Duo E6600. I’m using the DD MAG II LE 12V pump as the engine for this CPU cooler, a Black Ice Xtreme Radiator (with a Silverstone FM122 fan added,) a Single 5 1/4 Bay reservoir, and the two blocks the TDX and MC-TDX. Room temp was kept @ 20 to 21 Degrees C.

As can be seen, there is no great temperature difference with either TDX when the CPU is idle, but things change under 100% load (on both cores). We used Intel’s Thermal Analysis Tool for 2 hours to verify that this new block does make a difference. It may not be much, but the new block dissapates more heat, which can handle Intel’s Quad Core Q6600 and on. Cooling a Dual Core CPU with this block is no problem at all.
