Brand New Genuine AMD Athlon 64 X2 Heatsink and Fan with 4 Heatpipes

I assume the 4 pipe version would be even better.

This is a 4 heatpipe heatsink. There are 4 copper heatpipes, two each on opposing sides. Why do you say it is a 2 pipe version?

The reason I ask is because I am trying to figure out what I have. The heatsink has 4 heatpipes configured as the heatsink you link to. My heatsink has a 70mm fan also but has a slightly different lever (plastic cam arm) than what is pictured in your link. Overall, I'd say it is the same heatsink/fan as in your link.

On the side of my heatsink next to a heatpipe is "FOXCONN (or FOXCOMM or FOXCOM?) 2ZR71-086" and "2006 04 29". I found 2 references to "2ZR71-086" on google: a Japanese post concerning an FX-62 Socket AM2 Box (125W), and, a spanish text website about a X2 4600 someone got and was pleasantly surprised about the heatsink. None of the Foxconn website's heatsinks looked like mine.

I am a little confused in that my heatsink appears to be an AVC Z7U7414001 with a 70mm fan (but with a different plastic cam arm) despite Foxconn being tattooed on one side, and, that the current AMD heatsink has the 4 heatpipes all on the same side and has an 80mm fan according to this thread.

So, is my heatsink an "older model" or the current model? I am not thrilled with having a louder 70mm fan, presumably with less cooling power than the 80mm fans.

Take a ruler and measure the size of the fan. Is it 80mm or 70mm? Just the fan alone is a good enough reason to go for the 4-pipe one.

How are you measuring fan size?

The fan is in an asymmetric plastic casing. Without removing the fan from the heatsink, measuring top outside edge to outside edge the fan is 74mm X 80mm. I'm assuming this means I have a 70mm and that the extra mm's are due to design of the fan fitting on top of the heatsink requiring an extended plastic casing. As reference, my Yates Loon 120mm fans are 120mm measured from outside edge to outside edge.

(The black plastic casing which houses the fan is actually larger - 91mm X 80mm, but I only measured the proximate area around the fan proper.)

This is the one with 4 heat pipes and an 80mm fan.

Each pipe has two ends. It may be easier if you count the total number of ends you can see and divide it by 2.

The version with the opposing heatpipes and smaller fan is the older version. The newer version's fan is more powerful but is also louder. I have both models and actually prefer the quieter older one for daily use when I'm just running the cpu at stock speed.

According to the reviews of the two heatsinks/fans referenced by Navid, the AVC Z7U7414001 (older model and the one I appearrantly have) with a 70mm fan runs 48.1 dB at 3500 RPM (idle?) and increases to 63 dB at 5400 RPM (full load?). The newer model heatsink/fan has a Delta 80mm fan (not regarded as a quiet fan historically) was 44.5 dB at idle and 48.8 at load, though the author did not state what RPM's these dB's were recorded.

Since dB is an objective finding, I wonder if your finding of the "older" model being quieter at stock speeds (low load? and controlled ambient room temps?) is due to a subjective preference for the pitch of the fan noise. I am just theorizing and not meaning to insult you in any way, since i don't have both fans and you do!

I feel a little burned that I didn't get the "newer" model. I'm going to try out this "older" heatsink/fan, but I may get the "newer" model so that I can attach a 120mm fan for quieter cooling.

FYI:
Specs for the "older" model 70mm fan from AVC.com.tw - AVC DE07015B12U. AVC states 41 CFM at 5400 RPM with 44.8 dB. BTW, it is a two ball bearing fan.

A Review at OverClock Intellignce Agency has the DE07015B12U at 41cfm @ 5400rpm ; 44dBA and ~23cfm @ ~3100rpm ; ~30dBA. They found it to be on par with other HS/fans such as Thermalright XP-90 and Thermaltake Golden Orb II at stock CPU speed and voltage, but fell behind significantly when the CPU was overcloacked and at load. So, the take home message is the stock AMD "older" HS/Fan is sufficient for stock CPU usage. No real surprise here.

I could not find anymore info on the "newer" heatsink model's Delta fan, even on Delta's website. Must not be reading the model number correctly from the MadShrimp photo.

I'm trying to remember which one of my pipe AMD HSF was different than what the web had as a part number. I'm probably confusing people here, I'm saying that either my 2 pipe or my 4 pipe HSF was a slightly different design that what reviews showed. Adds another variable to the mix.

How are you going to attach a 120mm fan?
I hope my post did not cause confusion.

I bought this.

I bought a 120mm Yate Loon (M) fan. I installed the 120mm fan on this bracket in my case. The flexibility of the bracket allows the fan to run at high RPM without the vibrations transferring to the case and acting as an audio amplifier. The exact same fan installed as a case exhaust fan results in a lot more noise at the same RPM!

The 120mm fan in my case helps cool the CPU, the chipset as well as the voltage regulator on my 7900GT graphics card.
I run every single fan at a lowered RPM.

Using an 80mm to 120mm adapter. Never tried it but it should work in principle, given there is plenty of room for a taller and larger HS/fan in my case.

I have several Yate Loon 120mm RPM sensing fans from a previous good buy with NexFan. They will do 47 CFM at 1350 RPM with 28 dB. That beats the stock 70mm fan that came with my heatsink.

I suppose I could use a 70mm to 80mm adapter then attach an 80mm to 120mm adapter with my heatsink. I wonder how that would turn out.

Actually those are both 4 heat pipe models. I have both and they both have four pipes. Also according to your revies they both have 4 pipes.

You may be right.
It looks like the one with a 70-mm fan also has a total of 8 pipe ends visible. If that is the case, they both have 4 pipes.
Thanks for the correction.

i got the 70mm and the 80mm version im just not sure if I like the 70mm better but im still not sure just yet of switching from my xp90

AMD tech support states both are 4 heatpipe heatsinks, just differently configured.

People assume that the newer model, with the 4 heatpipes stacked on one end, is better but I have not seen any head to head comparison. Accoustically, the Delta 80 mm fan on the newer model is quieter at max RPM according to the MadShrimp review but I can only make apples to oranges comparisons on the HS/fans via different reviews since methods and equipment varies.

Since you have both models, what has been your experience with both cooling and loudness?

EDIT: I just posted this message and saw that you posted one while I was typing which sort of answered my question.

The cooling power VS. the crappy OEM that came with my x2 3800+ is amazing .

OC'd to a 250bus, it runs at 38C, 100% cpu load, fan @ 2700rpm. The original unit would hit 44C @ 5000rpm.
