Mac Thunderbolt 5 Dock Runs Cooler Than Pricier Rival
What You Need to Know
- CalDigit TS5 costs $400 and offers three downstream Thunderbolt 5 ports versus TS5 Plus’s two.
- TS5 features fanless aluminum chassis with passive cooling, staying barely warm during testing unlike TS5 Plus.
- Display support varies by chip: M5 Max supports four 6K displays, M1/M2 limited to single external display.
- TS5 includes braided Thunderbolt 5 cable in box, differentiating it from competing docks at similar price.
The CalDigit TS5 is a $400 Thunderbolt 5 dock that quietly outperforms its $500 sibling in at least one measurable way: it offers three downstream Thunderbolt 5 ports to the TS5 Plus’s two. That single spec difference matters more than it sounds when you’re trying to connect multiple high-bandwidth peripherals simultaneously.
The tradeoffs for saving $100 are real but mostly affect power users. The TS5 drops to 2.5 Gigabit Ethernet instead of 10GbE, loses dual USB controllers, sheds DisplayPort, and delivers less charging wattage across its ports. For anyone not running a NAS or transferring large files over a wired network constantly, none of that is likely to register day to day.
Thermal performance is where the TS5 actually surprises. The fanless aluminum chassis stayed barely warm during testing, a meaningful contrast to the TS5 Plus, which ran noticeably hot. Passive cooling in a Thunderbolt 5 dock at this bandwidth class is not a given, and CalDigit appears to have sized the enclosure well enough that it works.
Display Support Depends Heavily on Your Chip
The dock’s headline display capabilities only fully materialize with specific chips. Four 6K 60Hz displays require an M5 Max. M1 and M2 Macs are limited to a single external display through this dock entirely, and the M3 has its own carve-out where clamshell mode unlocks a second display that an open-lid configuration does not.
CalDigit includes a braided Thunderbolt 5 cable in the box, which is a small but genuine differentiator since several competing docks at this price ship with generic cables or none at all. The company also publishes a detailed compatibility chart mapping every Apple silicon Mac to specific display configurations, which is more useful than it sounds given how inconsistently this information is communicated across the industry.
At $400, the TS5 sits in a category where most buyers are making a five-plus year purchase decision. The backwards compatibility with Thunderbolt 3 and 4 Macs softens the timing risk considerably.
