Comparison of 560 gtx heatsinks.

post #1 of 5
Thread Starter 
I know heatsink and cooling design isn't the only thing that makes a card more overclockable (speedbinning comes to mind), but it's pretty important. I took some time to hop through a few reviews and save a few shots of heatsink backsides to compare them. Hopefully someone will find this useful.
Several edits, thanks to windfire. I also did a little digging on 560 PCBs. Techpowerup has several very detailed examinations of bare cards.


Reference Design
3 6mm heatpipes in radial pattern, with 8015 ball-bearing fan. Reference design calls for 4 VRM phases.
EVGA is based on the reference design.
PNY also appears to be reference based.



Zotac @ techpowerup
Merely 2 heatpipes in radial pattern. It's actually not 560 reference. Instead, the reference clocked Zotac appears to use the 460 reference cooler AND a shorter non-reference PCB with 6 VRM phases (seems similar to a 460 OC type PCB).
There is also a Zotac OC version that uses 3 heatpipes, I think that uses the 560 reference design. (Unconfirmed)


Palit @ techpowerup
3 Heatpipes custom design. Palit's PCB is also a non-reference 460-like design, being even shorter than the Zotac standard card. It has the standard 4 VRM phases.


Asus @ overclockersclub
3 8mm heatpipes divided into a finned section and a extruded heatsink section. It has HDT going for it however. The PCB is similar to the 560 reference design with a non-reference VRM section, with 6 VRM phases. Keep that in mind for guys buying waterblocks for cooling their VRM.


MSI @ overclockersclub
2x 8mm + 2x 6mm heatpipes. It's also nickel plated copper, not alumminum. The PCB is identical to the 460 Hawk design with 6 VRM phases. (this is not 560 reference)


Gigabyte @ techspot
Also 4 6mm heatpipes. This design uses exposed copper base and heatpipes. I cannot find a clear shot of the Gigabyte PCB. The backside hints that the Gigabyte design uses 6 VRM phases.



Galaxy white edition @ vr-zone
Similar to the Gigabyte design, minus one fan. There's another photo that shows the backside to be similar to the msi heatsink.


Galaxy anarchy edition @ hardocp
Unfortunately, i was unable to get the money shot for this heatsink. I would assume it's similar to the white edition, but I can't be certain (I only spot 3x heatpipe ends near the gpu core). The removable fans are a nice touch.

Gainward and Sparkle also uses quad 6mm heatpipes.

Hmmm, nice thread. Will check back from time to time since am looking forward to buying this gpu. Do remember to update this thread/post as newer models of this gpu emerge. Nice initiation. Rep+ awarded.

the imageshack link to the last pic seems to break every now and then. I'm not sure how to fix that. Reupload the source pic?

You can try that. And if that doesnt work, you have the last option to attach the pic with your post and get the link from the attachment window to place it inside your post.

Good work that should help a few people (+rep). There are a few inaccuracies though.

Let me add some supplementary info that should enrich this thread:
1. Reference Design
three 6mm heatpipes, 8015 ball-bearing fan
(http://www.overclockersclub.com/revi...asus_gtx560ti/)

2. Zotac has two versions. The reference one has a shorter length (210mm) while the OC version is of standard length (229mm). The reference version has one fewer heatpipe but it brings a more compact size, I suppose.

3. Asus' DirectCU uses three 8mm (not 6mm) heatpipes
http://www.xtremesystems.org/forums/....php?p=4719384

4. MSI's Twin Frozr II cooler has two 8mm heatpipes on the outside and two 6mm heatpipes on the inside (not four 8mm heatpipes).

5. Gigabyte uses four 6mm heatpipes as well

6. Gainward 's Phantom (both 1GB and 2GB) and Golden Sample models also use four 6mm heatpipes
http://www.gainward.com/main/edm/GTX..._GTX560Ti.html

7. Sparkle uses four 6mm heatpipes as shown below
