ChillDex Cools Valve Index Down On Those Hot Summer Days

ChillDex goals to lastly fill that gap within the entrance of your Valve Index whereas additionally fixing an issue.

ChillDex is an adjunct for the Valve Index HMD bought by Toronto-based engineer Kyle Fredericks for CA$50. We ordered ours when the Kickstarter launched again in January, and it arrived just a few weeks in the past. In that point, I’ve been letting the warmth from the skin in (and leaving my room’s fan off) when in VR.

All present VR headsets get heat, in fact. The warmth from the show panels alone is noticeable, and even PC VR headsets like Index have some onboard processing, with numerous chips to deal with duties like USB, audio, and monitoring.

When No Man’s Sky launched in summer season 2019, I most popular enjoying on Index as a result of wider subject of view, exact lens separation adjustment, and punchy audio. Nevertheless, Index tends to warmth up greater than different headsets. Mixed with the summer season warmth, I ended up utilizing the Rift S extra for lengthy periods.

ChillDex exists to try to unravel that, however its kind issue is barely potential as a result of the Index HMD has an adjunct slot within the entrance with a powered USB-A port.

Setup & Expertise

There’s primarily no setup concerned right here. Simply take out out of the field, slot it in, and it’s prepared for use. Fredericks says preserving the Index entrance cowl off will enhance cooling, however you possibly can maintain it on in order for you.

Two white buttons are current on the best aspect of the gadget, stacked vertically. By urgent them you possibly can improve or lower the fan pace throughout 10 ranges, with degree 10 being 7000 RPM.

When you press & maintain each buttons for just a few seconds, Auto mode shall be enabled. Auto controls the fan pace primarily based on the temperature. This function isn’t out there on all ChillDex Kickstarter items (it was an possibility), however is accessible within the model at present bought on-line.

ChillDex is marketed as “close to silent”, however that’s considerably of an exaggeration. When the Index audio system fall silent on a sizzling day, you’ll actually hear the followers whirring away- however the noise isn’t loud or bothersome, and it doesn’t appear to vibrate.

What About The Weight?

When the Kickstarter launched again in January, Index homeowners on-line raised concern in regards to the added weight.

Again in 2014, I (and plenty of different VR lovers on the time) connected the 32 gram Leap Movement sensor to the entrance of an Oculus improvement package, and this actually did make it extra of a ache on my face.

I weighed ChillDex at 23 grams, however in contrast to Leap Movement it isn’t on the entrance, it slots inside. The design of Index additionally helps right here. It’s the heaviest VR headset on the patron market- Valve’s philosophy accepts the burden, however balances it with a sturdy, nicely made headstrap cushioned with comfy, premium-feeling padding.

I didn’t discover any distinction in consolation, and even perceived weight, utilizing ChillDex.

ChillDex Evaluation Ultimate Impressions

So, does it work? Merely put, sure. ChillDex makes the Index cooler on a heat day, because it dissipates a lot of the warmth that builds up contained in the headset itself.

Don’t anticipate an adjunct like this to be a silver bullet although. You continue to have a 800 gram VR headset strapped to your face, so warmth remains to be getting trapped, simply much less of it. Given you possibly can’t really feel the burden, there’s an auto mode, and it may be disabled at any time, if you happen to’re utilizing your Index within the warmth, ChillDex is really useful.
