The Cool Core is a zirconia-glass insert that sits in the IQ3's vapor path between the oven and the mouthpiece. Its thermal mass absorbs heat from vapor before it reaches your lips, cooling it by up to 50% compared to DaVinci's previous models. The result is a noticeably smoother draw — cooler, cleaner, and less harsh — without reducing terpene expression or vapor density.

Pre-chill it. Remove the Cool Core before your session and place it in the freezer for 10–15 minutes. The zirconia retains cold temperature well, and a pre-chilled Cool Core delivers vapor that reads almost uncomfortably smooth — especially effective on the first few draws before the device fully warms up. This is the most underused IQ3 technique and one of the most impactful free session upgrades available.

The Cool Core doesn't have a fixed replacement schedule — it's made from zirconia-glass, which is durable and non-reactive. Replace it when you notice flavor degradation, visible discoloration that doesn't clean off, or cracking. With regular ISO cleaning, a Cool Core lasts many months of daily use.

Wipe it with an isopropyl alcohol (ISO)-dampened cotton swab after every few sessions. Resin accumulates on the zirconia surface and affects both cooling efficiency and flavor clarity if left uncleaned. Do not submerge the Cool Core in ISO for extended periods — a brief soak followed by a rinse and thorough air dry is fine for a deeper clean. Let it fully dry before reinserting.

No — the Cool Core is designed specifically for the IQ3's vapor path dimensions. It is not compatible with the IQ2, IQC, or MIQRO-C. For vapor cooling on those devices, the DaVinci Hydrotube water tool attachment provides an alternative cooling method via water filtration.
