1. Cooling Performance - a CPU cooler is composed by the following 3 parts:

A combination of effective H/S and efficient fan - T.I.T.I. introduces users less noise, slim size and best performance multitude Dr.Thermal cooling solutions for both DIY market and System Houses. (check our product category for further details)

2. Quality -

  1. "E-Attachment" system - less work to be done, just a flick of a lever, you can just perfectly mount your cooler onto the socket.
  2. Appealing appearance and design: glittery colorful outbox design, nice care has been taken as well inside the box to avoid any severe damages during transits.
  3. Flexible Fan Replacement: Performance freaks with bad hearing will be delighted to know that the Dr.Thermal extrusions can accommodate any fans you want, should you want to upgrade to something a little faster or quieter.

3. Value/Price-

T.I.T.I. brings its customers with surprisingly innovative product design and cooling performance with satisfying prices.

4. Customer Feedback -

After waves of feverish reports and feedbacks from many review sites and users, Dr.Thermal serial CPU coolers are highly rewarded and welcome by the customers - especially the overclockers. T.I.T.I. will continuously put efforts on innovating and designing new products and solutions to meet the customers' needs.

T.I.T.I. constructs the Thermal LAB with its industry aspirations of perfections and innovations. Consisted of the Temperature Measurement System, Pressure Measurement System, (and thermal Video System, and other test facilities in the coming future), the LAB is considering to acquire more reliable and dependable figures and statistics during thermal experiments.

Chart 1
Temperature Measurement System
With software running full power, we measure the Heat Resistance and build up its database under 100% CPU operating.

Chart 2
Pressure Measurement System
With Pressure Measurement System, it is easy to read the pressure of the clip, and the effect of the clips to the temperature variation.
