[Guide] Air Cooling Questions Answered Here! (Updated 8/16/10) - Page 107

post #1061 of 1086
So glad I found this post. The tip is to heat up the screws first to ease the thread creation - works a treat and saved me from endless sighs smile.gif

BTW I also found that keeping track of which screws were used to create the grooves and using those in the same holes when screwing it back on worked best.

If their heads are being worn off, use a bigger screwdriver and apply more torque #0 screwdriver is what should be used. Not a tiny piss-ant screwdriver tongue.gif

Yep, basically the same length. And a good strong screwdriver is most definitely needed, haha.

Also, there are self-tapping screws that have cuts running down the length of the screw, beginning about halfway down and deepening to the tip. Save a set of these for tapping threads, then use non-tapping screws for the normal attaching jobs.

"Performance Fans:
Performance fans are generally used to cool radiators and CPU coolers. Keep in mind that connecting these performance fans to your motherboard is generally a bad idea as they may pull too much power and fry your motherboard's fan header. (Check your motherboard user manual for exact specification ranges)"

I just bought two SP120L fans to use as case fans and replace the fans that came with my corsair carbide 200r.

Is it a bad idea to hook these two sp120l fans onto my mobo system header?
on my mobo, the rear system header has 4 pin while the front has a 3pin.

That is okay! smile.gif You can throw a 3 pin fan on any header it fits on, as long as it doesn't draw more current than the max rating for the header! In this case, you're golden! thumb.gif

How do you determine what is the max rating for a fan header, if there is no published specs?

What would the max rating for a fan header be on a LAPTOP?
(Header on laptop is 3-wire, fans are 3-wire)


Would it be safe to add a 2nd fan of the same specs? (EG: Doubling the current draw, the stock fan being a 3-WIRE FAN, 5vdc, pulling .35amps)

On a DESKTOP it is expected the fans, might be upgraded to a fan that pulls more amps. On a LAPTOP I would assume while there is a safety margin built in, the designer assumes the fan won't be upgraded, the fan will be replaced with exact spec'd fan and for sure a 2nd fan won't be added.


Any thoughts would be appreciated on a control scheme on adding a 2nd fan to a LAPTOP.

Seems like no-one has any info they'd like to share on how to control a 3-wire fan.

i can put my SP120L fan onto my system header?

how do i know if its okay to put a certain fan onto the mobo or not? since the guide says to NOT put fans onto mobo

Have you contacted the manufacturer of the board you are talking about?

In general what is being said is fans that push more air (Performance fans, and fans which have to push air thru restrictions) draw a good deal of current and that you need to verify with the motherboard vendor how much current the fan header, or headers are rated for.

*Note, Vendors will rate components differently. As a rule designers try to put in a safety margin of say 2 to 1 to compensate for transient loads, wear and tear.
Good company will rate with a 2 to 1 safety factor, other companies will rate the component without a safety cushion.

IMO it's best to use a controller (Relay) in which does the "heavy lifting", the motherboard just sending a signal to the controller.(Relay)


In your earlier post you stated "on my mobo, the rear system header has 4 pin while the front has a 3pin."

The 4-pin header should allow you to connect a powered PWM controller. Signal comes from the 4-pin PWM fan header on board, POWER for the fans comes directly from the powersupply so there is no danger in burning up the fan header.

PS: For desktops while searching for info on fan controllers for motherboards which do not have a 4-wire header I believe I saw 3-wire fan controllers.

Q: What model, mfg , system, motherboard /model rev number are you talking about? Have you contacted the manufacturer? (I would suggest contacting them via e-mail, and then re-posting what they say...
(Post "details" like you'd like to run across. EG: Post model numbers, what rev number the motherboard is, details, specs.)

this is the mobo i have.
So is it safe to put my SP120L fans directly to the mobo system header?
also, since my rear system header on the mobo has a 4 pin, that means i can control the RPM right? while the 3 pin one will always run at full speed?

Is this safe to use for removing thermal paste from my CPU?

http://www.amazon.com/Philips-SVC1116G-Screen-Plasma-Screens/dp/B004PYD9I2/ref=sr_1_1?ie=UTF8&qid=1394006433&sr=8-1&keywords=lcd+cleaning+phillips

I have one at home

Also, which paste is better, the stuff that comes bundled with Noctua CPU fans, or Arctic Silver 5?

Yes it is ... It's really only 0.18amps per fan.
