Ghetto Mods

This is very bad (given) advice. People, do not drill holes in transformers for better thermal performance. Your asking your house to be burned down with something like this. I mean i'm not an expert in relation of electronics but you could short the transformer by doing this.

There's no need for any better flow; i mean the thing is cool, and did'nt caused any issues after having a fan running at 7V. It's just a cheap inverter and with cheap stuff usually comes cheapening out on design. Its just rated for what it does and dont expect alot better.

Noooo, I meant holes in outer plastic case so that the components inside have a better air flow. If it starts burning, holes in outer casing will make zero difference.
 
Oh,

Well, there are "open sidevents" as you can see and you can feel a minimal airflow coming out of it. Really it keeps the transformer alot cooler then before.

Why and how? As long as the housing being given holes is removed from the electronic parts there is no danger. Now of course you need to take it apart, but otherwise no issues.
 
Just brought DDR3 but it has bend pcb, i dunno how come it bends
Then i try to make it straight by putting bluetooth speaker on it and leave it over night

Then, it wouldn't be ghetto isn't it :P

I have a ghetto mod incoming for NR200P... Well it's as common as zip tying two fans but I consider it borderline ghetto. Damn Cooler Master, why can't they make the fan mount normal.
 
Just found in the wild, not PC related

Let's see... low profile, no mounting holes and the smallest fan I've got is 80mm...

Snug fit! Before the fix it would overheat and crash, now 53 C under load :cool:
 
@Valantar He might of only had the one available.
 
Modified this case to

Modified this case to house a 240mm reservoir with push pull on top, and made it to house a 360mm with full push pull in the front for when i upgrade my cooling :). it started as a standard cuk mantis case.

itll look a lot better when i get around to finishing the paint job on it.

Are you aware of what thread you're in right now? Lol

Are you a magician? He wants to use that fan on it but is worried if he glues it that he wont be able to re-use it later. Unless you can magically turn 1 fan into 2 then he would have to buy another fan to do both jobs. At least unless he wanted to modify a 120mm to mount there somehow if he had an extra one laying around.
 
Two hefty rubber bands in x formation sez i :D:pimp:
 
Rubbing alcohol dissolves superglue/PVA glue, so gluing it shouldn't be an issue in that regard. But glue is far less ghetto than the zip tie + twist tie combo above imo.

I bought a new 2000VA UPS to kind of, upgrade the old one i had modded. When i got back home, i powered it on, to note that nothing would happen. Like it was dead. After a small inspection i realised that the battery's inside the unit where "dead" and the thing must have bin in the shellfs for a good 2 year or so. Since i threw away the reciept while having a coffee at starbucks, i stumbled upon refilling of UPS battery's. Bottom point: battery's dry out over time and the capacity / voltage gets worse to the point they die. Since this thing has'nt bin used and just depleted itself for over 2 years being in stock i kind of had a chance to revive those 2x 9A battery's hooked up in serie (24V).

Opening them up was fairly easy, pop off the plastic cap and the rubber caps and you'll get this:

Looked pretty dry to me, so i went towards the store to get distilled water and due to the lack of a proper pipet a simple ketchup bottle with nozzle, lol.

I think per battery around 170ml of fluid went in, and some more after shaking the battery's and halfway charging them up.

At various points i measured the voltages; before filling it up it woud'nt pass the 7 volts really, but now they where actually at around 11v and a very tiny bubbling noise coming from the battery's. There's life! So after another hour the voltage measured 12.05v - which is around 3.6v or so. After cleaning them up, putting things back together and slapping back the cover on, it was time for a leak test, which is to prevent any fluids coming out or so, but as i suspected nothing happend which is a good sign.

They still need a bit of charge - the thing is'nt really fast, takes approx 7 hours to get 'm at 90% of their capacity. Proberly a full night for being at 100%. I managed to run a 1000W toaster so far for a minute which is'nt bad. I guess the recovery of such battery's depends on the sulfation that happens on the plates once they are exposed with air or so. Proberly because they are sealed.

Trying to align 1mm thin fan frame with 1x2mm fins would be a royal PITA, nevermind gluing it.

It's not as difficult as you might think and it works well.

And what if I needed that fan again?

The nice thing about super glue is that in certain applications, it's slightly brittle characteristic comes in handy when you want to break things loose later. The fan will just pop off with a bit of gentle force. Or you could just buy new fans..
