Danger Den TDX 939
Clawhammer... just the name makes you feel powerful. Of course since the
Clawhammer has debuted it's pretty much gained ground as the processor to get
acquainted with. It jut so happens that right now for not too much more than a
bill you can grab a lower speed one and overclock it. but sometimes overclocking
those lower speed processors can give you quite a headache when you're cooling
isn't up for the task. Rest assured there are literally tons of different
cooling arrangements, but none of it compares to something from the Danger
Den. Whether if its replacing or adding to your existing water cooling
arrangement, Danger Den always has an answer for you. Some people think that
water cooling can be dangerous, hard to put together, and unreliable, but Danger
Den has been active in the water cooled PC market for years, and speaking from
personal experience I have yet to experience any kind of failure from a product
they have either manufactured or carried over the course of 5 years. Starting
from the first design of the Maze waterblock, Danger Den has continuously sought
after improving its efficiency year after year, and now has become known as the
TDX. Sure a few months back we tested a TDX of the Pentium 4 variety, but we're
here today to relive the glory of the TDX on a Socket 939 platform. Lets take a
RBX performance with just two (2) Barbs!
Includes - Complete Block Assembled with Top and O-ring,
and #1 Accelerator Plate.
Ships with High Flow 1/2" Fittings and Stainless Steel
Additional Nozzle Package include #2, 3, 4, 5, and one
Socket wrench included to remove bolts.
Brass Top Version ships with (2) springs and (2) spacers
to reach the AMD specification of 75lbs of hold down force.
Machined Lapped and Touched up to 1200 grit.
Pressure tested before shipment to 85psi.
The Accelerator Nozzle
Nozzle is a feature that allows you to fine tune your water loop so that you get
the optimal benefits of a RBX/TDX waterblock. Accelerator nozzles ranging from
#1 to #5 can be purchased separately in order to do this but more important is
that the TDX is already configured with nozzle #1. For multiple blocks this
nozzle is the best to run, but if you are considering running just a CPU block
#3 may be best. The way the nozzle works is a secret but upon a closer look it
looks as though the variance between the nozzles lies in the arrangement, depth,
and height of the plate that the pumps water flows into the block.

Another view from inside the block
The TDX is a beautiful piece of work and is a token of how
well Danger Den focuses on quality even though their demand is high. Changes to
the RBX/TDX blocks are readily apparent. The fittings have received a size
adjustment so you can fit your loop inside your case a bit easier from their
height decrease. Along with the Nozzle resizing comes the use of O-rings around
the nozzles instead of traditional Teflon tape or pipe goo... the interesting
aspect of the TDX is how modular it is now to take advantage of the accelerator
The bottom of the block reveals traditional Danger Den
craftsmanship. As stated before in the specifications each block is touched with
1200 grit. As of lately Danger Den has been using a protection tape covering
after each block is manufactured, and as you can see the dark line reveals where
its split so you can easily remove the covering.
We used a Epox 9nda3+ for testing with a 3500. As you can see
all you have to do is remove the back plate form the bottom of the motherboard,
install the studs, and that's pretty much it. More detailed instructions are
downloadable from Danger Dens how to section located
Installed and ready to go. We used Arctic Silver is its a
proven thermal solution. Its interesting to see how much room the TDX saves over
previous blocks, and without losing any cooling efficiency either. Just a rule
of thumb, always cut your hoses to size after your components are in your case.
This will alleviate any kind of problem with the hose being too short or long.
So long as you take your time and think everything over carefully, anybody can
put a Danger Den cooling system together.
We're pretty much ready to go at this point. Since most of
today's games are more video card dependent we went with a dual block
arrangement using a Maze 4 GPU block that we reviewed earlier
here. Instead of the traditional CPU->chipset->GPU cooling arrangement we
followed the advice from Danger Den's Dan Stephens to go from the pump->GPU and
Here you can get a better idea of the change in our testing
configuration. Pump->GPU->CPU->Radiator->Reservoir... The yellow hose was a used
piece we had used in our UV dye test setup, not too pretty but after a few days
with some bleach in the reservoir should make it clear again...
For our test setup we had a new sparkly 3500 Winchester core to
play with, along with a Epox 9nda3+. We used the x800 Pro, Crucial Ballistix
PC-3200 (2x512mb), and our Lian Li PC V2000 case which holds a Danger Den BIX
Micro II with twin 80mm Sunon HS fans. So a quick rundown...
Epox 9nda3+ Motherboard
AMD Athlon 3500
Visiontek Xtasy x800 Pro Videocard
Crucial Ballistix PC-3200 2x512mb Memory in Dual Channel
Lian Li PC-V2000 Case
Fortron Source 500W Power Supply
For our testing we didn't really have too much around to test
against other then the OEM cooler, and if you don't know right now you should,
there is no comparison to liquid cooling. With that said we also decided that
since we are an overclocking site we best find out the maximum overclock we
could get out of this setup with the Danger Den setup. After a power supply
change out we were able to finally get our setup stable enough to play a bit in
the BIOS. After a couple of resets we reached a fairly good setup seeing as how
we were able to get our 3200 memory into 4400 territory even at CAS 2.5 without
a vdimm mod to the 9nda3+. Running at a HTT of x4 and the 3500's default multi
of 11x, 250fsb was attainable but not as stable as 245. We probably could have
pulled of around 248 or so, but 245 is a nice stable setting that will survive
under hours of gaming and general use.
cool, our Crucial RAM is WAYYY over spec, and at its specified
2.75v too!! So how well does a 2.2Ghz 3500 perform at 2.7? Lets check Sandra to
Super PI Results
...and again. Wow... 32S beats our
existing 4Ghz P4 record by 2 seconds!
A temperature of 37 Celsius is very reasonable considering we
are cooling not just the CPU, but the GPU as well, which according to ATI Tool
is at 35C.
The Danger Den TDX block never ceases to amaze us. A completely
stable overclock is what a good water cooling system is all about and the TDX
delivers. The 3500 is a great CPU which keeps coming down in price and its so
nice to see that AMD's socket 939 platform is ever increasingly becoming
affordable to us Overclockers. We deserve these price drops, and seeing as how
you can literally take a Maze 4 block and bolt on a new top for under $20, I
would seriously consider the TDX AN investment into your overclocking future.
Water cooling can take on many forms, but it isn't until you see what you get
with a Danger Den that you can really see why people get the results they want
from water cooling. For the newcomer to water cooling, take note of this, and
perhaps hit up the guys at Danger Den to take on your cooling needs, you won't
be disappointed... ClubOC HIGHLY recommends the TDX...
