Motherboard/ Fan Problem

[PentiumPower514]

Ok, heres a STUPID question:

I just got the Asus P4P800 Deluxe, and I have 5 fans (4 Case, 1 CPU). There are only 3 Fan connectors (2 for "Chassis" and 1 for CPU) How do I get all 4 Case fans connected to the MoBo?

Thanks,

First of all you do not need 4 case fans! And second putting all four fans on the motherboard is not a good idea since you can come close to overloading the fan header on the mobo. My rule has always been no more than three fans on the mobo, so you have the CPU, Chipset, and one case fan, or if no chipset fan two case fans. However it is always much better to connect the fans directly to the power supply.
But once again you do not need all of these case fans, unless you like noise. With a P4, and a standard drive arrangement all you need is one case fan exhausting out the back.
And to everyone else, this is the type of stuff beginners do after reading all the BS about needing a ton of fans and if you do not have your CPU below 30degrees C you need to add fans. I just wish people on here would start stating that if the machine starts acting funny then add a fan, try it, and if needed then add another fan. Instead of repeating the BS that that you need all the fans you can get!

Yea, I agree with morris. Especially since this is a Pentium. You ned one or two case fans for this set up.

Anyway, there are connectors that daisy chain the fans. Also, some fans plug into the power supply (nice) and thus cannot be monitored but who cares?

OK, I'll trash the POS fans that came with my case and use my new ones

Im sorry for wanting to use 4 case fans LOL people

are you talkin about me or the CPU? I'm not THAT much of a noob

OK. As i understood it, u sejest for pentium 4 no more than 1 or 2 fans on the back of the case.
My question is how can i lower the CPU temperature, if not by the fans. And what is the optimal (best) temperature for 2.4mhz cpu? Mine shows 56-58 .C

Tnx

In most cases the P4 will only need 1 or 2 case fans like with my P4 2.4C it runs so cool ( 32C ) I prolly only need one exhaust fan. I do have another P4 2.4B on a P4PE BP board that runs from 45C to 55C and needs more cooling in cases like this it might be best to get an aftermarket HSF. I use the VANTEC VP4-C7040 and it does a nice job and is not too loud.

The temperature your CPU and system runs at depends a lot on what the ambient room temperature is...if the room is hot, the CPU and system will run hot. What are your room temperatures like?

But 56-58C is pretty high for a P4. What motherboard are you using? Check to see if the heatsink retention ring around the socket is lifting off the motherboard. This will lessen the pressure of the contact between the heatsink and CPU and reduce thermal transfer and you're CPU temps will go up.

Cricket, Can you get repair kits for the retention ring?
If so where?

I did find this one, but are there others?

[Cricket]

I haven't heard of any, but I think it was glc who mentioned replacing the push pins with nylon nuts and bolts (or regular nuts and bolts with nylon washers)...those should hold the retention ring securely.

Cool THX Cricket, I'm going to go to the shop and get some hardware and see if I can get the retainer fastened a lil more secure, I did have one corner that had a little play and may have been my causing my heating problem on this one mobo.

[lil Jimmie]

Well so far no luck the temps are still high with the stock HSF and two case fans. When I change the mobo in my wife's PC I'm gonna try another P4 ( that I know runs cool) in this board to see if it is the board or cpu.

lil jimmie,

I found more of the "stock" retention ring here.

Alittle more expensive but no modification needed. I keep a check on the retention pins and so far so good.

Thanks Kubie, I may just go ahead and order the one at Jab-Tech it looks to have backing support to prevent any flex in the mobo around the socket.

Well, the temps in my room are high, usually. And my board is MSI 850E MAX.
Su u sujest 2 funs, 1 in back 1 in front?

[Cricket]

Yes, 1 fan on the front and 1 fan on the rear is that standard fan setup. But if your case allows for 2 fans on the rear it might be a better to run 2 exhaust fans and no intake. The 2 fans exhausting will create a vacuum in the case and cool air will be naturally drawn in. This setup is usually less noisy too.

[PentiumPower514]

what about 2 fans exhaust out the side?

[Cricket]

I've never tried it like that, but no reason why you couldn't experiment with your case fan setup. If your motherboard BIOS has a health monitor with temp readings, you can setup your fans anyway you want and then run the system hard for a while. Check the temps to see how the fan setup is working out. Then change the fan layout and run the system hard again and check the temps. Keep this up until you find what works best for your particular computer.
