SpeedFan works great in this case though. It has its own little subroutine for fan scaling which works great. As long as the fans are plugged into a 3 or four pin header, SpeedFan can usually control it.

Which motherboard are you using, by the way?

It's an Asrock G41M-S3. I have never had speedfan work. I think the only machine that it can control the fans on is my P3 based Celeron HP machine (I am not joking)
The Asrock "OC tuner" works to set the CPU fan but not the case fan.

You're doing it again, why are you doing it again? 🤣

P5B is my favourite 775 board, it served me 2006-2014 and now serves my wife. The integrated sound died a few days ago though, but what would you expect from a board working several hours every day for 9 years? I dropped in an SB Live! 5.1 (surprisingly, there are drivers for Windows 7 x64) and it sounds good. It's kind of amazing, a 12-year old soundcard, a 9-year old mobo, an 8-year old CPU with a 7-year old GPU cope very well with any task she throws at them 😀

Sort of unrelated, but how does the SB Live hold up in Win7? 😊

Not worse than the original sound, TBH. The driver/mixer are 3rd party because Creative never made W7, let alone x64, Live! drivers. So it's a little tricky in software, but otherwise great. The card in question is SB0220.

Asus P5Q Premium is shitty? Could you please elaborate on this one a bit more?.. 😲

Hint: My main rig is based on this MB (built in mid 2009), and still works without a single major or minor problem.

Well got my GA-G41MT-S2P up and running..
Intel Xeon X5460 engineering sample
8 Gb DDR3 1333 Ram
Currently running Linux

It's plenty fast enough for desktop uses. Especially with a 180 GB SSD.

Did you update the microcode on the board's BIOS?

Just curious, why did you specifically purchase a C0 stepping chip and not an E0? Did you get it at a good price? Also what kind of temps are you getting with it, seeing as how this is a 120W TDP model?

I have that chip because I work at Intel and I wanted a ES chip. Board didn't need a Microcode update. Booted up just fine but I updated the microcode anyways.
With a Noctua NH-9UB cooler it stays about 35C when running stresslinux live cd

If you don't update the microcode, some of the features don't function. You can confirm this with CPU-Z before and after the mod.

Just a minor nitpick, but a 3 pin fan can't be controlled (via PWM), it can only be monitored. The 3rd pin monitors the rotational speed. The 4 pin fans are the ones that can be controlled via PWM, as that's the function of the extra pin. This is also why you're allowed to put a 3 pin fan into a 4 pin header, because the pin out is the same, it's just that the 3 pin fan wouldn't be PWM capable. Although if you hook up 3 pin fans to a fan controller that can change the voltage going directly to them then you can slow them down or speed them up that way, but that's different.

My motherboard has 3-Pin headers which can be controller. Whether by dropping their voltage or through use of some waveform I am unsure though. I have only ever seen this on ECS boards such as the PF5 or the strange little KM400 variant used in the Acer Aspire T120.

Yes, I've usually found that the 4 pin headers are not only PWM-capable, but are usually also wired to be able to control 3-pin fans by monitoring the speed and then dropping the voltage accordingly.

The way I understand it, with PWM, the third pin also monitors the RPM, but the fourth pin sends the information to the logic controller on the fan PCB. With three pin fans, the logic that controls the fan speed is on the motherboard. On my particular Foxconn board, the PWM control in Speedfan has a few second delay, but it's no big deal.

I just tested to make sure and strangely, SpeedFan won't control the one 4-Pin header, but it will control two of the many 3-Pin headers. I never use this feature however. It's 100% all the way for me.

KV2 3-Pin headers also work as far as I remember.

It has to be configured properly. It would not work for me either, until I did this. I can't remember exactly what I had to do, but I can check for you if you want.

It's not really important to me. Like I said, I never use this feature anyway. I only ever tested it because the option was there and I was curious as to what it would do. I prefer to run my fans full speed at all times as the sound is less annoying and it extends the life of the hardware and makes the system more tolerant if a fan fails somewhere - I always over-engineer the cooling system, I even modify laptops to supply their fans with a constant 5V so they run flat out.

The CPU fan speed can be decreased to tolerable levels but the case fan is still noisey 2400 RPM.

When the mobo lacks CHA_FAN control, you can daisy chain all fans with Y-splitters ...

· If CPU_FAN header is 4-pin PWM, all fans must be 4-pin PWM (3-pin non-PWM fans will run uncontrolled @ 100%).

· If CPU_FAN header is 3-pin voltage-regulated non-PWM, all fans must be 3-pin (4-pin PWM fans will run uncontrolled @ 100%).

CPU fan headers can withstand 2A of current. A typical 120mm case fan draws 0.15A tops:

Thus CPU_FAN header can feed a dozen fans without problem.

2A? Most of my manuals state between 250ma and 500ma but it seems to vary widely, so be careful.

The fan you posted as an example (Arctic Cooling F12) is actually the model I use. They have rather weird bearings on them. That particular model actually has three connectors. A 4-Pin connector that plugs into the motherboard and a 4-Pin header to daisy-chain another fan and a 3-Pin connector to connect the tachometer to the end of the chain. I run two 120mm versions from the CPUFAN header - one on each radiator.

Edit: Like this;

So you're saying you could hook up 13 of those fans to a single header? I seriously doubt that will end well. 😵

OBSOLETE MY ASS!!! MY 775 Q9550 is running a 1ghz OC @ 3.85 ghz with DDR THREE ram (12gb) and a GTX 770 i plan on running GTA 5 at lovely 50-70 FPS. it's one of the fastest CPUs of it's time and is still extremely usable. you can even do 771 mods and use XEONs which over clock to 4-4.5 ghz with the right board and chipset.

I just set up my mom with a Pentium D 945 and after a 6 hour burn in with Prime 95 my OC at 4.08ghz is running nice and steady. Windows 7 32bit is rather snappy and the only thing that will be holding it back after I swap the SSD that is on the way will be the 2gb of DDR2-400. Even the 1gb HD4650 is more than enough for her needs 😀

Not the fans. Besides it will make the system clog up with dust and fur significantly faster (its a serious problem with 4 cats)

It's a 3 pin fan plugged into the 3 pin CHA_FAN plug. It can even measure the speed but not control it.
Strangely enough, the old OEM board could control the fan speed but that board died.

Well a 1 GHz OC is really big. In most cases, you can't overclock nearly that far.

I don't see Core 2 being obsolete, I said that several years ago and clearly was wrong but it comes down to how well one uses what they have. I have seen people look at current gen i5 as not being good enough which is just absurd.
