If you want to spam your Sandevistan like David Martinez from Cyberpunk: Edgerunners, you’ll need a Legendary Sandevistan Heatsink to reduce your cooldown dramatically. This guide explains exactly how to get it, how to craft it, and what stats you need to pull off a true Edgerunners-style build in Cyberpunk 2077.
1. What Does the Legendary Sandevistan Heatsink Do in Cyberpunk 2077?
One of the most popular builds in Cyberpunk 2077 revolves around the Sandevistan Operating System. This type of Cyberware lets you slow time on command, giving you an edge in both combat and stylish finishers.
The Sandevistan, like any manually activated Cyberware, has a cooldown period before you can use it again. Installing Heatsinks is the best way to reduce this cooldown and keep your high-speed combat flowing.
Each installed Sandevistan Heatsink shortens the cooldown period by 4 seconds. When combined with other mods like the Legendary Bioconductor and a Qiant Sandevistan Mk.4, your cooldown can drop as low as just 2 seconds, making the transition between activations almost seamless.
2. Why the Edgerunners Build Needs a Legendary Heatsink
Since the release of the Netflix series Cyberpunk: Edgerunners, many players want to replicate David Martinez’s rapid-fire Sandevistan usage. In the show, David can trigger his Sandevistan on demand, appearing unstoppable during fights.
While that level of instant activation isn’t technically possible in Cyberpunk 2077, a Legendary Sandevistan Heatsink lets you come close. It’s the key to minimizing downtime between bursts of slowed time, keeping your combat as fast and lethal as possible.
3. Where to Find Sandevistan Heatsink Crafting Spec in Cyberpunk 2077
Sadly, no Ripperdoc in the game sells a Legendary Sandevistan Heatsink outright. The only vendor who offers a Heatsink is the Kabuki Slums Ripperdoc, and he exclusively stocks the Uncommon variant.
If you want to craft higher-tier Sandevistan Heatsinks, you’ll need the Crafting Spec. You can purchase it from the Arroyo Ripperdoc for €$1125. Once you have this spec, you’ll unlock the ability to craft Sandevistan Heatsinks from the Cyberware Mods section of the Crafting menu.

4. How to Craft a Legendary Sandevistan Heatsink in Cyberpunk 2077
Even after buying the Crafting Spec, the rarity of your crafted Cyberware Mod depends on your Crafting skill progression. You’ll need to hit specific milestones to unlock higher rarities.
Crafting Requirements for Legendary Sandevistan Heatsink
Here’s how Crafting rarities unlock:
- Rare Crafting Specs unlock at Crafting skill level 9.
- Iconic rarity unlocks at Crafting skill level 18.
To craft a Legendary Sandevistan Heatsink, you must reach at least Crafting level 18. Without that skill level, you’ll be stuck crafting lower-tier mods.
Engineering Attribute Limits Your Crafting Skill
Don’t forget that your Crafting level is capped by your Engineering attribute. If your Engineering is only level 12, your Crafting skill cannot go higher than 12 either.
To craft the best Legendary Cyberware Mods, you’ll need to invest attribute points into Engineering and push it to at least level 18. Otherwise, you’ll be locked out of high-tier crafting entirely.
Best Sandevistan Builds Using Heatsink
The Legendary Sandevistan Heatsink is a must-have for builds focused on frequent Sandevistan activations. It pairs perfectly with the Qiant Sandevistan Mk.4 and the Legendary Bioconductor, creating cooldown times as low as 2 seconds.
If you’re chasing a build that mimics David Martinez’s unstoppable speed, prioritize reaching Crafting level 18 and installing multiple Heatsinks. This combination lets you stay in slow-motion combat nearly nonstop.












Some guy
you need to level technical ability to 18 not engineering high speed. engineering has nothing to do with crafting that is smart weapons and other random junk. also it’s misleadingly confusing to talk about the ripperdoc that sells the green heatsink, no one cares, you can just craft the green heatsink automatically by getting the crafting spec, so just remove that part of the article. people will glance at it and go to that ripperdoc and realize you led them to the wrong place. just say “go to arroyo ripperdoc, buy crafting spec, article over, stop chasing word count and convoluting it

That’s the wrong video choom it just shows a guy finding an common beats I’m in a chest.
