Ghetto Mods

[newtekie1]

It is becoming summer in my part of the world, and my office is getting hot. The air outside is cooler, but how do you get it in the office? Setup an old power supply that I keep around just to test things because "the fan is sometimes noisy", use a bent paper clip to jump it so it says on, and put those fans in the window!

Also, there is another bonus ghetto mod that is rather well known that I didn't mention. Can anyone spot it?

All into one molex because it carries enough current?

Can you sense the pitch of my voice getting higher like Stewie Griffin. ?

Nope, but you are very close.

done this one myself last year
"" i approve ""
you might use some Meccano to tie the fans together
Vibration can cause them to walk and fall off ledges ect
Fan guards could be also fitted those fans are like spinning razor blades
(personal injury and blood losing pain can be inflicted if one forgets and just picks them up happened to me so i fitted guards )

flick switch instead of paper clip or does PSU have its own on off switch

paper clip
see above for improvement idea

Luckily the paint on the ledge is kind of...rubbery...for lack of a better word, so they stay in place.

I cracked my thumb nail on the fan all the way to the left before...hurt like a son of a...

PSU has a switch on it, or I could just unplug from the wall which is right under the window.

1 technical level
2 amount of cable ties/ sticky tape/ stuff lying around used
3 finesse, the more attempts made the better
4 time taken
5 finished result/effectiveness


10 not for the inexperienced, frail of mind or heart
7 there was enough stuff left lying around after the mod to make up for it, a "garnish " of electrical tape would have sealed the deal.
7 no way was this a first stab, abracadabra job
5 no accurate data
10 excellent i expect, even better if the window is open


10 kudos points awarded on behalf of your coworkers who no doubt get in early just to get the window seat.

49 massive points from me
you just added that you hurt yourself during the mod, im upping my score to 54


@newtekie1
Edit. after lengthy discusions with the union representing your colleagues, on safety grounds the 10 kudos points are currently under suspension due to ongoing safety concerns

Can you really just dremel the longer connector and it still work?

It would be better to dremel the back of the PCI-e slot out on the motherboard side, assuming there's clearance on the board. This would allow the 16x slot card to fit the board, but not completely kill your chances of running 16x in the future.

I get kind of uncomfortable about modifying hardware I care about, so I just used one of these to fit a HD 3650 in my dad's Dell.

I'm not too worried about it, the card is an older 7600GS, so I didn't really care if I killed it and it doesn't really need the x16 bandwidth.

 

[CAPSLOCKSTUCK]

Nope, but you are very close.

PWM fans have too many cables...you only need a pos and a neg for each fan.

Hence the dangly bits . Noted in the mintes of the meeting as... " trip hazard 4/b

Nope, all the fans are standard fans, no PWM. But you are looking in the right area.

I'll give a hint: The fan all the way to the left is a 5500RPM beast that sounds like this.

clutching at straws now.......have you reversed the polarity to quieten it down?
Theres definitely something odd about that molex connector.

Do like me. I put screwdriver to pry the molex connector of the 12v and transfer it to the 5v. It cuts the rpm and the sound but since 5v always seems to have way too much Amps for what a system needs use it for fans.

It was the first thing I noticed when I went back to look for the "Easter egg" you left us, you have the +12V lead running to +12V and the ground lead run to +5V so the fan is running at 7V.
I'm surprised nobody else noticed.

yes, it was the first thing i noticed too........................................runs away, egg all over his face.

 

[JunkBear]

So you did plug fan on 5v only now?

 

[newtekie1]

No, the ground is plugged into the 5v, so the fan runs at 7v.

 

[OneMoar]

No, the ground is plugged into the 5v, so the fan runs at 7v.

ever heard of a fan controller ?

 

[JunkBear]

You do with what you have that's why it's ghetto mod.

 

[Random Murderer]

I have quite a few controllers lying around, yet I always seems to come back to just wiring my noisy fans in at 7V... it's a lot simpler from a cable management and fan speed management standpoint. Hell, you can even still use PWM control at 7V, it's just a lot touchier since a lot of PC fans don't start up until almost 6V.
Besides, where's the ghetto-ness in doing something the way you're supposed to?

thats all find and good untill you blow a power supply up

Ha, ok.
Been doing it for years with no issues, dozens of PSUs, various combinations of fans and other loads inside and outside of PCs. Obviously you don't understand electricity enough to understand what's going on and how modern PSUs see crossload all the time in normal circumstances, no different from running a fan like this. So I'm not going to bother trying to explain potentials and crossload, etc., just know that I do know what I'm doing.

Honestly @OneMoar, you've turned into kind of an asshole lately. Are you feeling OK?

Ghettoness is on the way to Happiness,

This man speaks the truth!
