Windows 7: Overclocking help; your suggestions, please.

I assumed if the rear case fan was plugged into SYS_FAN2, a 4-pin connector which the CM is, that it would have MB control of speed. Apparently that isn't the case. The MB manual only mentions the CPU_FAN having MB control. Can this 4-pin be plugged into a 3-pin?

This pic is from the Gigabyte manual. My SYS_FAN2 is @ 384RPM. But, how can this be changed manually? The manual mentions some software Easy Tune6 that can control fans but after install it wont even open.

I'd think that the option CPU Smart Fan Enable would have an option for Manual..if it does it may allow you to individually configure Fan speed.
Check for updates for easy Tune and check your Bios to see if it needs to be enabled..probably under a Tools Tab.

4pin to 3 pin..unsure..never tried it on so unable to comment ...Only fan that has PPM ? or whatever is the CPU fan..case/sys fans are set at one speed unless changed in the BIOS.

lol pity there isn't a BIOS standard..mines Asus and slightly different

You should be able to get the 4 pin to at least spin on a 3 pin header, but the RPM monitoring function will likely be lost.

I'd avoid that Easy Tune app and anything else on the provided CD. Those apps are all known to be shaky or worse.

Agree, ditch the Gigabyte apps.

Try Speed Fan, haven't used it for fan speed control, so can't confirm it will work.

My CM 212 CPU cooler fan works fine, variable speed.
I think simmo is right about the headers that control fan speed, check your manual.

I tried Easy Tune6 & it didn't open. Then reading up on this I ran across a suggestion to check if BIOS has been updated. It could be that Easy Tune would only work with current BIOS, not an outdated one. Current BIOS is F2 & checking with Gigabyte, it was now up to F4. Well, tried to install F4 but it rejected 64-bit. So, I installed @BIOS from Gigabyte (I've used @BIOS with success before) & did an update. It did find F3 so I installed that. Rebooted only to find it wouldn't boot at ALL.
Now what!!!? Kinda panicked after that but wound up posting for suggestions elsewhere at this site. A suggestion was to check the BIOS settings as updates usually revert back to defaults. I should of remembered that! Anyway, new BIOS defaulted Integrated Peripherals/PCH SATA Control Mode to [IDE] instead of AHCI, needed for SSDs. Made the change & it booted fine. Needless to say, no more using Gigabyte's HELPFUL apps.

Back to fans. The only differences between CPU_FAN & SYS_FAN2 (see pic) is pin # 4. With CPU it's for speed control & for SYS it's for reserve. Doesn't sound like reserve has anything to do with speed control but could be wrong.

According to BIOS PWR_FAN is running @ about 1500rpms. I figure using the first 3 pins of the CM fans 4-pin connector to plug into SYS_FAN1 as the first 3 do match up properly (see pic).

I'll try Try Speed Fan 1st, then using as a 3-pin.

Reserved means not used, looks like the only variable speed fan is the CPU fan.

Glad your BIOS flash was successful, have never tried @BIOS due to the many warnings on various sites not to use it. The Gigabyte forum moderators say 'Don't use @BIOS'.

It wouldn't startup in IDE mode because the drivers aren't installed, good catch.

I have my exhaust fan connected by Molex with the separate yellow RPM wire connected to the Sys Fan 1 sensor pin (second from right). The exhaust fan is shown in BIOS as “Sys Fan 1” and in HW Info as “Power” fan with a fixed speed of about 900.

If the mobo connector is used, the fan is shown as Power fan with only 490 rpm in HW Info. So it can be monitored with either connection, but the Molex method shows closer to true RPM.

My exhaust fan is NOT PWM. It's supposedly 800 rpm fixed.

If you connect a PWM fan by Molex, I don't know if you can still adjust fan speed with Speedfan. I tried Speedfan at one time on another motherboard and never got it to work.

What are your remaining problems?? Just getting the Coolermaster to change speeds? Worst case, you ditch it and run the Antec on high or medium?

Staying under 65C under a full rendering load is, IMHO, perfect.
Especially if you plan on doing lots of encoding.

Downloaded & installed Speed Fan. Also plugged case fan into SYS_FAN1. Case fan is pumping out air - lots of it. Speed is over 1900rpm - constant. Front fans (2) are about 1400rpm. As far as noise goes it's definitely louder but not as loud with the Antec fan @ max of 2000rpm. I haven't tried Speed Fan to lower speeds.

One difference with the new BIOS is Hardware Info locks up the PC. Can't do anything until I manually reboot; even control/alt/delete wouldn't work. I uninstalled Hardware Info. I don't know if it's worth trying to revert back to BIOS F2. I'm not out of the woods yet!

I certainly wouldn't flash a BIOS just so I could run a utility program that has substitutes.

What version of HWInfo32 are you running??

I am using 3.7.1.0 dated March 22, 2011 with an F4 BIOS, without issues.

Have you tried to freshly install HWInfo32 after you last updated your BIOS?

Are you satisfied no further cooling issues?
