Off topic slightly, but is the use of HBM in the new Nvidia cards gonna mean the same form factor as the Nano?

They could yeah.

Which NV cards? Those for later this year or 2017 possibly. The upcoming cards for both companies are going to use GDDR5X.

Can anyone suggest an overclocking software for over volting these cards? Apparently MSI afterburner is not recommended, but Sapphire Trix is.
Also, what would be considered a suitable 120mm fan as a replacement for the stock one? That includes PWM fans that can use an adapter for the Nano's mini fan header, or a standard fan that can used from summat like a Zalman speed controller. I can get hold of some sheet aluminium easily, it would just need to be cut and bent to size and shape to act as a shroud, with a bigger opening for a 120mm fan.

Just got hold of a "Gelid" pwm fan adapter for vga cards, so I just need to source a suitable fan

I bought this one some time ago to replace Corsair's own fan on Hydro H50 liquid cooler. It is very quiet -> https://www.overclockers.co.uk/noiseblocker-blacksilent-pro-fan-plps-120mm-pwm-1500rpm-fg-032-nb.html

I've got four noiseblockers as case fans, would this version be more preferable on a gpu heatsink as I've read its advisable to have a "focussed flow" fan, or is that a load of hooey?

It makes sense, but I am not into fans to be honest so can't advise you on that. But I know Silverstone used those "focused flow" fans in their Raven RV02 PC case for maximum cooling effect, so there is that.

You'll need at least 1500rpm to keep it at or under 80°C

Thats good to know, makes the choice easier.

Right, had a chance do some playing around with the Nano and I've come to couple of conclusions. First, its quite important to keep the temps below the throttling threshold, in the case of my Nano, it's 80c-82c degrees, any higher than that and it throttles by about 50-60mhz on the core and performance really does suffer as a result.
Secondly, a small increase in core overclock gives quite a significant increase in performance (to a lesser degree, so does overclocking the Vram but not as much). I don't recall my old 780ti performance increasing that much for a similar increase in core clock, ie: 50mhz. Now this might be a "placebo effect" but my scores in unigine "heaven" benchmark, went from:
1643 up to 1775 when using the following settings:
This is nudging my old heavily overclocked 780ti.
This is using the latest MSI after burner software.
Vcore: default
core speed: 1075
Power limit: 50%
Vram: 545
Fan: 100% (deffo audible, but I've gotten used to it funnily enough and noise tends to stay unnoticeable when gaming with the volume, though will differ from person to person and what they're prepared to put up with)
I'd say water cooling is deffo the way to go for high clocks, either custom loop or AIO if/when it becomes available, or a good mod would be to slap a decent, high airflow 120mm fan on it (the latter I'll be looking into myself.)
Any questions, ask away, opinions, criticisms, flaming all considered to be valid

Wow, that's quite loud for a 120mm fan. How fast does the stock fan on one of these run? I though they were supposed to be quiet...
Soldato
I personally don't think you'll need any fan that'll idle at 1500rpm meself, I reckon a 120mm fan running at,say, 1000-1200rpm would shift about the same amount of air as the 92mm jobbie on the Nano, maybe more, depends how good it is at idle.
It's out. They call it the Fury X.
Soldato
The stock fan ranges between 1500rpm and 3000rpm, idle speeds of 1500rpm is the lowest speed within the PWM range of the fan. Typical fan speeds under load are around 2500rpm which isn't quiet, but isn't that loud either.

Not at idle, but you'll need 1500rpm + to keep it under 80°C. I've tested with single and dual 92mm fans, and with a single 120mm fan, both just manage to keep it at 80°C with the fans at 1600rpm (92mm) and 1500rpm (120mm).
The bottleneck is the heatsink.

Stop.

Well the noiseblocker I've ordered max speed is 2000rpm, the same as my case fans, and they're fairly quiet at max speed too so heres hoping.
Curious as to the behaviour of your cards. Mine and looking at few other people's on other sites it seems once I increase more mv then 18mv performance actually takes a dive in both fps and firestrike scores. So while I can maintain a higher clock speed 1140 for example with higher mv, the overall performance is worse then saw at 1120 MHz stable with +12 mv.
Curious as to others cards in this.
