25-30 more that what? (see below)
uguru - fan control software in bios/windows (on PRO and MAX boards - IP35PRO is £30 more that IP35) or
uGuru panel - a display panel for a spare drive bay - showing fanspeed / temps with USB & Firewire ports.
The first is excerlent if you have more that 2 fans inc cpu cooler, as it's will 7v mod them for you
and the pro/max abit boards have more that just uguru for the extra money (xFire, eSATA)
The second is ok if you like displays, and makes more sence of your question - personally I say no
Only ever brought Abit boards that had uguru onboard, never needed the panel.
i have a mobo with that uguru software you can do loads in it i only use for fan control and its awesome. my mobo has 7 fan headers so i can control 7 fans with it/ you can set an low temperature and a high temperture and then what speed you want the fans to run at while at those points anything from 6v to 12v. the cpu fan is slightly different. that one you still have the low and high temp but you set the speed as percentage 30%-100%.
you can then monitor fans speeds aswell as all the temperatures in your case. also all the voltages. its also an on the fly overclocking tool but i never used that dont trust it lol prefer to use bios.
but for fan monitoring its awesome just have to make sure you buy fans with 3pin headers to monitor the rpm. as i forgot once lol
fan speed ramps rather than running just high & low.
In the Windows GUI for uGuru you have a no. of factory preset profiles & 3 user configurable profiles which you can jump between at a mouseclick & you could configure those to each have different behaviour.
uGuru is the best mobo manufacturer supplied solution but that doesn't mean that you can't find a better aftermarket solution if you are willing to pay for the better specialist hardware which it sounds like you may have done.
As long as you can defined 3-4 ranges of temps/fan speeds for 3-4 fan headers, sounds perfect!
As you / buff said above - each profile has only two states (high/low)
but you have 3 custom stats to play with - aka idle (6v-8v) surf/office (6v-9v) Gaming (8v-12v) and can switch between then with two clicks if uGuru in the system tray
Pre watercooling my system was under 100% cpu load 24/7 and the fans at 6v in winter and 8v summer never hit that 10v high once(but then I don't own a hot GPU)
on mine it definitely varies between them, it doesn't just run at either the max/min settings.Oh! That doesn't sound very good! 'BUFF' implied it was not just high/low when he said, 'fan speed ramps rather than running just high & low.'
on mine it definitely varies between them, it doesn't just run at either the max/min settings.
the profiles encompass overclock settings as well, not just fan control so as shadowscotland says you can have e.g. an underclocked, normal & differeent overclocked setups.
