Hooking up fans

post #1 of 4
Thread Starter 
Well, I recently upgraded to an Intel P4 Fire-breather (Prescott) and I'm now realizing that I'm going to have to put a bit more thought into cooling. I've got the layout for my fans figured out, but here's my question: what is the best way to HOOK THEM UP properly? Here's what I'm facing set-up wise:

*FANS*
2 12cm 3-wire Fans (Front and Rear case)
1 8cm fan on HDDs (2-wire)
1 8cm fan feeding funnel to CPU fan (3-wire)
Auxillary signal lead from my Antec PS (to monitor PS fanspeed)

*HOOKUPS*
FRONT and REAR case fan, on mobo
two fan-only leads from my PS
everything else will get hooked to signal-less sources

*SYSTEM INFO*
Mobo - Intel 945GTP Express
Power Supply - Antec Truepower 2.0 430W

My biggest debate right now is which fans to hook up to the two fan outputs on the mobo itself. I just want to get this sucker to cool itself effectively, which is damn hard here in Arizona during the summer. At least it's dry, I guess. So yeah, any help or advice would be appreciated! -d

Welcome to the forum mate Go to "User CP" at the top of the page and fill out your specs in there.

I can understand your climate and the importance in cooling and air flow. For me the best bet even though there is plenty of fan headers on my nf4 board was to get a fan controller. You give it power and you can set it and forget, it does not rely on Windows to give you a warning that there is a problem with a temperature or a fan not running correctly. You can set profiles, warning alarms for different things, just about anything that you need to do monitoring wise. They are pretty cheap and do a great job and do not need Windows or an OS to make them work, totally self sufficient

The general rule of thumb is get air in and get it out, so 2 fans in and 2 out, depending on the fan's flow you could have 3 in and only 1 out. Experimentation is the best bet here, no 2 rigs are exactly alike, similar but not.

Thanks for the welcome tuchan... I never thought about a fan controller. (hate to admit it, but I didn't know they existed!) Brilliant idea though, so I went ahead and ordered a Vantec 4-channel unit. I've had little luck adjusting my fanspeeds via software, so this seems like the way to go. My fans could certainly use more juice. Don't get me wrong, I don't want a PC that sounds like a turbine, but I do want to know the thing's alive.

My new cooling setup seems to be working well, I've dropped about 7oC at idle, holding steady at 49oC, which is still too hot in my book. My old system (using the same case) never had cooling problems, even with the mild overclock I had on it, and the side panel more or less open. When I purchased my case (PIC), I was drawn to it for two reasons: a) It's badass, and b) I figured the mesh sidepanel would be great for ventilation. Soon after I upgraded however, I realized that it simply would not allow for effective airflow. So I covered all of tthe mess, sans the 8cm square for a powered CPU funnel. I also read up on proper airflow technique, and placed my fans accordingly.

Damn I'm long-winded. Time to wrap-up...

So I've got my system almost to where I want it. I'd still like to OC it, but short of going with watercooling (too expensive for now.) Maybe I should put this all together and make a guide for other poor saps stuck with hotheaded Prescotts. Anyway yeah, thanks for the tips tuchan

You could always upgrade your heatsink, if you have the stock heatsink on there, there is almost no amount of fans that can lower your temps that much. The best option for you, if you are willing to spend a little money, would be to look into a high quality hsf. The best air cooler available right now is the big typhoon

http://www.newegg.com/Product/Produc...82E16835106061

looks like you have bad timing though, it only cost $47.00 a few hours ago with free shippings.

But that is the best cooler out there, it rivals many cheap watercooling setups. With that on my cpu, my idle temperature is about 28 degrees, very cold for air.
