Port Replicator Series 3 fan?

Hi all, I am considering buying a port replicator for my t420, but I also want to have an external fan blowing on my thinkpad when I play games, for instance. I'm wondering if the port replicator series 3 has an internal fan built into it, and if not, would an external fan below the port replicator be of any use in cooling the laptop? Thanks!

Re: Port Replicator Series 3 fan?

no there is no internal fan. With the replicator attached, there is little point having a fan underneath.

Would the laptop heat up more easily than it would off the dock then?

Re: Port Replicator Series 3 fan?



I'm not aware that we really see any adverse heat issues with a laptop on a dock.  In some cases, people may dock and use and external display and driving 2 or more external displays could work the GPU(s) harder and lead to some increased system temp, but I don't think it is an issue for most people.

The design of dock support full air vent using standard air vent built in ThinkPad. No blocks etc.

Therefore no need for additional fan even if you use 100% of CPU and 100% GPU.
