Zip ties to attach LEDs?

[Divan_24]

Has anyone tried using zip ties instead of screws to attach the LEDs to the heatsink?

not zip ties but 2 part apoxies work just fine. autozone sells 2 part (jb weld) apoxies for $5-$10 and i know they work. i have used them for leds on a heatsink. the only issue is im not sure how im going to get the led off if i ever need to replace it.. hope this helps

Sure, it might work, but it will offer zero benefit in terms of thermal conductivity. I wouldn't use epoxy because of this reason as well. Use thermal adhesive.

I was planning on adding thermal grease and using the zip ties to hold them tight. I don't want to use epoxy since its a pain removing them.

I wouldn't use zip ties, the leds and heatsink will probably heat up enough to weaken the plastic. Altex carries Artic something or another thermal paste/adhesive which is used for attaching heatsinks to cpus. It works very well for attaching leds as well and no screws are necessary. I currently have several leds attached with only that paste.

It's tacky, but I wouldn't trust that. If you are just using paste, you should use hardware to secure them, otherwise adhesive is necessary.

I tried using just the paste and I would find some LEDs hanging. I will be running 4 120mm fans n try to keep my heatsink as cool as possible.

I'll give it a try with a couple of LEDs adding paste to increase thermal conductivity n securing them with zip ties. Let's see how it goes.

Thanks for the help! :)

It does t seem that you took much of the advice, which was to not use zip ties.

When I ran a shop I wouldn't let my technicians use electrical tape. Proper connections and heat shrink tubing. There's nothing professional about half stepping an installation by making do. I'd use the screws and thermal grease.

I understand the desire to build your own stuff. It's fun and the product is something you can be proud of. But there are those out there that think it's a half measure used by some to save a dollar and I think that's perpetuated by half *** jobs performed by DIYers.

Build it right, bro. Make it look professional.

I will be using adhesive. I did say I was going to try with a couple. I'm just curious n wanted to experiment

wouldnt the zips melt? leds give off some decent amount of heat close to the emitter

[Divan_24]

Do nylon washers used with screws receive any damage from the heat of the emitter? Never used them before

Just use thermal paste, it's not too hard to get a razor under the LED and pop it off the heatsink.

Edit: How often do you plan on removing them? Using zip ties would end up probably killing the LEDS from the heat build up.

Every 50000 hours :Big Grin:

Nylon hardware is fine.

I used the epoxy on mine, came out pretty good. Has any one noticed a increase in algae after switching to LEDS

[Divan_24]

I followed everyone's advice and just used epoxy. :)

Pfcreed I had a cyano outbreak when I added WW but it was gone when I got rid of the nutrients
