is a low resistance set-up really a hotter vape?

hey guys, I have been vaping these sub-ohm coils for a long time now, infact it seemed like when I first started it was kind of taboo in a sense, people kind of thought I was crazy and that the whole sub 1 coils were just way to dangerous. it defiantly has changed now and has become more mainstream for sure. now, information is being given back & forth on the in's & out's on how to do all this sub 1 stuff, when I first started giving information on the how to's, I was looked at as someone who was potentially helping people to kill themselves, anyways enough of the nostalgia and more to the heat generated by a sub 1 coil. I hear a lot of the word "HOT" when people asking about these low resistant coils, I have even heard of people trying these and saying they were much to hot for them. from my experiences, which range as low as 0.6 to 1 Ω I don't think of them being hot at all, and that's why I initially got into low resistances in the first place. when I first started vaping gennys I did the whole vv 6 volt thing for a short time and found the vapor to be to hot, I then remember seeing something saying that a thicker wire has less resistance then a thinner wire therefore it is a cooler wire, also seen something saying that at a given length a thicker wire will be cooler then a thinner wire at the same length. this is why I tried low resistance vaping, and for the most part I did notice that the vapor wasn't as harsh and was much smoother, so when I think of low resistance I don't think of the word HOT, I think of it as smooth. now technically, am I correct in saying that a thicker wire is not as hot as a thinner wire? I have always thought that a 1inch piece of 28g will run cooler then a 1 inch piece of 32g. I know theres a lot of sub oner's out there now and want to hear from you comparing the heat of a sub 1 coil compared to the heat of a regular coil.

Thicker wire runs cooler for sure.

Cram 30w through 32ga and it'd be like satan's butthole.

that's what I have always found for sure, but you know what I mean? it seems like low resistance vaping is associated with more heat, I just read another thread asking the difference between low resistance vaping and high resistance vaping, all the answers said that low resistance vaping is hotter at the same wattages, I don't see it.

All else being equal, I think 1" of 32 and 1" of 28 would be about the same temp. The 28 takes more power to heat up, but more power would be going through it due to its lower resistance. At equal power, yes, 32 would be hotter. Or with each at lengths which are equal resistance, 32 is hotter.

SLR can be made hot or not-so-hot depending on wire gauge.

I think some people may see the wattage these coils can handle and need to perform optimally and equate that to hot....that's 16 watts HOLY <<>> that must be hot! In reality the higher wattage is just heating a larger diameter coil, plus the wick in many cases takes some of the heat from the coil. If someones getting a harsh...harsh vape on a low ohm genny it's most likely an issue with the build or airflow rather than the watts being pumped through it.

My low ohm gennys are no hotter at doubleish the wattage than my mass produced attys and catros, they just deliver a smooth, full, more satisfying vape.

Funny you should mention this, Vap. I'm just trying sub 0.5Ω for the first time, today. Nope. Not hotter. With my air holes @ 1/16 + 1/32 + 1/32 and maybe .4Ω of 26gKan, its cooler than running .7 on a single 3/64 air hole. I'm using a Phoenix XL, the chamber of which tends to get hot, and it ain't. Cool and flavorful. All about proportion, I guess.

interesting, with all the coils that I have done they have all been with gennys and not drippers. although the principals are the same, I often have thought that maybe in very tiny spaces that have smaller wicks, that maybe things were a little different. I don't have any experience in the dripper devices so im not really sure how such high wattages would react in such tight spaces. thanks for the feed back

good point on the wicks, they do absorb the heat. this can definatly be the difference in slight temperature differences for sure. when I vaped ss mesh I always seemed to have more mesh with in my wicks then most, my wicks were very solid rods of 500 mesh, this is like a heat sink that might have kept my gennys cool. I guess if you have a flimsy wick it would be a little warmer for sure. now I do the porous ceramic and they are really solid and also absorb the heat, so my low resistance coils in ceramic are pretty cool as well.

Also, if your wick works properly, your vaporizing more juice so the temps don't really increase. Just more vapor and flavor. I'm vaping a double twisted 28ga .6 ohm coil on SS mesh, and it is not hot - warm at best. Wish I had the b@lls to drill out the air hole on my new Cobra.

you know a lot of people have asked this very same question about drilling out either the air hole or wick holes of the cobra, to my knowledge I haven't heard of anyone doing this, especially the wick hole. totally agree on the proper vaporization in the coils. I know that sometimes when setting up a new coil, things aren't finely tuned in yet, and you will get heat, but once its dialed in 100 percent, sweet, thick slightly warm clouds. and there more white then thinner wire gauges, is this just me? I find that a thick wire at low resistance produces a whiter cloud then a thinner wire at higher volts, maybe its just me.

Well, now, I've plugged 3 caps to date. All 1/16 back down to 3/64 or to dual 1/32. today I drilled out to 1/16 on a cap that had 2 other 1/32 holes as well. What I mean is, I HATE big air holes . . . . . . . . until the resistance gets low enough. For me, that's at .5-.6Ω.

I think it's what I've gotten used to and the Cobra seems a little tight. AGA-T2 drilled to 1/16 is my norm.
