Hey guys I'm fairly new to sub ohm. I know most things I should know concerning what batts to use. Ohms law and etc. but I'm just new to vaping sub ohm. I have an igo w at about .5 ohms and got a efest v1 2000mah 18650 so amps is fine but the problem is. I know my rda is supposed to get warm but so is my k100 tubing. I take out the battery and its not hot. It's just the tube. Anything to worry about?
Sub ohm question

To me it sounds like your k100 is literally absorbing the massive amounts of heat from the atty. If it were me, yes I would worry... You do not want that battery getting too hot...
Thanks for the info. Should I invest in a better mod? Or is there a way to fix this?
That is the main reason I tried and have avoided sub ohm coils. The heat weirded me out a little bit.
You need to figure out where the heat is coming from. It could be from the battery, but you said it's not which is great. It could also be from the RBA, or the switch. Which end is getting hot first will probably answer this. If it's the switch, take it apart and make sure all contacts are clean. If you need to sand a contact surface (if you can't get it clean with a alcohol wipe for example) do so only with very fine sandpaper or emery cloth and only as much as needed to just clean it.
If it's coming from the RBA end, are you chain vaping and the atty is heating up the mod? If that's not it, you might have a dirty contact issue from the 510 connection.
I have been running a K100 for months now and never had the tube get hot. Be careful it really is not the battery. Best of luck with it!

Take a couple drags, don't burn yourself but feel your set up.
If you mod, especially the button, is warmer than your atty you are experiencing arcing. If not, then it's fine. You could get a drip tip with a delrin heat stop and/or open up the airflow a bit (if you haven't already).

Thanks. I tested and its the rda gettin ht then transferring to the tube. Battery isn't getting hot
It can be tough to fit a sub-ohm coil in those RDA's and not have it get hot. They are either close to the sides or close to the bottom. And it's all metal.
Even on my current IGO-W setup (not sub-ohm) it gets quite hot. Air holes are part of the solution, true. But so is coil placement and also...maybe think about cotton underneath the coil between the coil and the bottom. It will insulate a bit. It acts as a wicking material too. Just don't let it get dry.
I found that a cotton base helped when I was doing cotton wicks on the IGO-W.

I think it's because since I have quad coils some are on the bottom and the others on the side. Since its not the battery is there anything to worry about? I always let my rda cool down after it starts to get warm
P.s. thanks for all the output. New to the fourms

I sub ohm at .8 my dual is at .4 I don't like anything under .8.i will be rebuilding the .4 it get way to hot. I have a sigelei 8. The top can get warm if i am pacifying it. It doesn't bother me to bad. My .4 is a little weird for me.
FWIW, cotton under a micro coil is now known as a "diaper" (at least in the big micro coil thread)
He finally tells us he has 4 coils.
Gee, heat, na, your'e kidding!
You've found the source.

A member here, pdib, shares the simple solution: A single micro coil around a 1/16" drill bit or 16 gauge filler needle, consisting of 8 wraps of whatever gauge and type wire you need to get the resistance you want. I've played around plus or minus, dual coil, etc. but keep coming back to this. It's "the law" for my daily driver RM2 RDAs. I use 26 AWG Nichrome 60 for 0.5Ω on the home Grand and 27 AWG Kanthal A1 for 0.8Ω on the commute/work Grand. I've played around with different wick material but keep coming back to organic cotton balls. The flavor is off the charts with either setup and the TH can be moderated with coil height. The atty gets no more than warm.
What I would worry about is heat damage to the plastic insulator for the positive, center post and in your case the 510 connector. I have done that to my AGA-T when pulsing out shorts. It's not good to be breathing in that stuff, but then I was not vaping it. You are. What worried me more was the plastic degrading to the point where it could cause a hard short there.
I'm going to be trying micro coils soon. IMO that could be a much nicer solution all around.
Yeah, whats with those insulators being friggen plastic!
They should be that heat-tolerant silicone.

The problem IMO with silicone is it's so soft it would be easy to damage it by screwing down on it too hard.
Now, interference fit ceramic inserts could be the ticket for this application. But forget about that in $12 RDA's or $22 RBA's.

The silicone oven mits I have are actually harder than the insulator. It's like plastic, it's not a liquid.
Have you seen the cookie sheets made out of them?
