What exactly is equity crowdfunding?

Equity crowdfunding gives any company an opportunity to raise capital from the public, where investors hold partial ownership in the company and have the opportunity to profit if the company does well.

How Equity Crowdfunding Works

A business that wants to raise money opens up an equity crowdfunding campaign on an SEC-registered online platform.

Individuals can invest a relatively small or large amount of money and in return, receive an ownership stake in the company

The business then uses the capital it raised to grow.

In time, investors may profit from their investment if the company grows and becomes more successful, and the value of the investment holdings increases.*

Equity crowdfunding is a relatively new way for companies to raise capital; it was signed into U.S. Law in 2016 (JOBS Act for CF Regulation)

The purpose of equity crowdfunding is to help small businesses just like us.

We’re proud to be part of this revolutionary entrepreneurial way of doing business, and it aligns perfectly with our game-changing ProSiphon technology and our desire to create a strong, rebel community of like-minded tech enthusiasts and entrepreneurs that aren’t afraid of being unconventional to push technology forward.

Embrace a Cooler Future!

IceGiant has designed the ProSiphon Elite to provide superior cooling and incredible reliability. It's unique, thermosiphon technology utilizes two-phase heat transfer to keep your CPU cool and safe. With an industry leading 10-year warranty, you can rest assured that the ProSiphon Elite will provide many years of day one performance.

Superior Performance Extreme Reliability

ProSiphon Technology

Superior Performance
Extreme Reliability

Designed for the higher heat loads of today’s most advanced chips, IceGiant’s technology deploys a more efficient strategy to battle heat with the use of phase change science.

There are no internal moving parts in the Elite that could break down.
By relying on good ‘ole gravity to operate rather than a mechanical pump, a prominent failure point of coolers is removed completely.

  • Heat from the CPU boils liquid inside the evaporator - vapor flows up to the condenser
  • Cool air flows through the condenser and liquifies the vapor
  • Gravity drives the liquid back to the evaporator, and the cycle repeats
IceGiant's patented ProSiphon technology can handle the most powerful CPUs out there

Best yet, our technology will show day-1 performance on day 3,650.
Our 10-year warranty sets the gold standard for CPU coolers.
(this warranty also covers the 4 low-noise fans that come with each Elite!)
