Dual fan 560s

post #1 of 3
Thread Starter 
So I'm looking at GTX560Tis, and there are a lot of ones with nice-looking non-reference coolers. I was wondering if anyone had any input on the noise levels of these three cards, as well as overclockability:

MSI GTX560Ti 1GB Twin Frozr II
Asus GTX560Ti 1GB DirectCU II
Palit GTX560Ti 2GB Sonic


Also, what's considered a safe voltage when overclocking a 560?

I have 2 of the TwinFrozr II 560Ti's in SLI, running OC'ed @ 950.

The twin fans on each card are very quiet at idle, only when I started stressing the system do I begin to hear them.

Initially, I thought I was hearing the 4 fans at idle, turns out it's my power supply fan, that's the only fan that's noticeable in my rig.

Out of the three listed it's a tough call because only the Asus has VRM heatsinks but I don't really like the cooler on the Asus. It uses a normal copper direct touch heatpipe and aluminum fin section for the right fan but over the actual core it just has as giant hunk of aluminum, at the very least it's an inelegant way of doing things and at the worst it seems cheap and shoddy. Because of this they use different fans for the right and left, less blades over the hunk of aluminum, but despite this I've still heard some bad impressions with the acoustic performance of it. Which would make sense seeing as it has different fans working with vastly different resistance but both at the same speed.

So out of the ones you listed I would go with the TFII with some of these heatsinks for the VRMs, or the Palit if you would like the extra VRAM. Either card would be a good option once fitted with those VRM heatsinks. If you run into problems fitting them they make slightly shorter ones but I would rather just splay the fins out to alleviate any vertical clearance issues, that way you keep the same greater mass and gain some surface area for heat transfer. Here is a picture of the PCB of the MSI TFII and of the Palit, you can see that it should be a pretty easy job fitting the heatsinks to either of those.

The other option would be to get what is most likely the best 560ti on the market out of the box, it already has some cooling for the VRMs in the form of a unisink which isn't spectacular but should be adequate. Either of the three cards I recommended should be pretty comparable in both price and performance once you add those heatsinks to the other two, so if you feel you'd like the extra VRAM of the Palit or find a good deal on the TFII then there's no reason not to get those.

As for the voltages I believe the limit for reference PCBs in AfterBurner is 1.1v which is only 13mV higher than the 460 and I saw plenty of people max those out even without VRM sinks and saw very few if any problems arise from it so I wouldn't worry too much about 1.1v or 1.125 which I think might be the max for the Hawk.
