Select from as thin as grease to as thick as gap pads

Consistent performance. Robust in the harshest environments. Performance may increase as aligned Carbice Nanotubes settle and further lower resistance.

Negligible. Carbice Nanotube hair maintains rebound capability over time & cycling.

0.08 – 0.15 cm²K/W 3 – 6 W/mK Negligible Horizontal only

Thin

Performance decreases. Grease dries and pumps out.

100% compression set. No rebound.

0.06 – 0.15 cm²K/W 5 – 8 W/mK Negligible Horizontal only

Thin to medium

Performance decreases. Develops air voids and/or pumps out.

100% compression set. No rebound.

0.35 – 5.0 cm²K/W 5 – 50 W/mK Negligible Any

Thick

Performance may decrease. Can de-wet under cycling due to compression set. Loses structural integrity under high pressure (eg bolts).

Low to moderate. Hard pads: 1 – 5%. Soft pads compress more but can set up to 40%.

0.20 – 0.50 cm²K/W 5 – 10 W/mK 120 – 1800 W/mK Any

Medium

Consistent performance. Unless the stiff film tears/breaks under (eg different expansion rates)

Low to moderate. 3 – 15%.

Ice Pad™ provides better long-term cooling than other TIMs

Electronic devices experience an increasing number of heat management challenges:

  • Smaller and more powerful electronics lead to thermal expansion mismatch
  • Thermal expansion mismatch causes electronic malfunction and shortens lifespan
  • Conventional TIMs fail to dissipate heat over time due to dry-out, pump-out, and formation of air voids
  • Electronics de-rate, degrade, and are disposed as e-waste after a short time

High-Performance Grease C-SAM Analysis
Grease was applied only at the center of the interface (within the dotted circle).

Initial install
After 50 cycles
After 2,000 cycles
Inspection after disassembly

Takeaway:
After only ~50 cycles, the grease has completely dried out.
 


High-Performance PCM C-SAM Analysis
PCM was applied over the entire interface.

Initial install
After 50 cycles
After 2,000 cycles
Inspection after disassembly

Takeaway:
Air voids migrate around interface with PCM.
 


Carbice Ice Pad C-SAM Analysis
Ice Pad IP150 was applied over the entire interface.

Initial install
After 50 cycles
After 2,000 cycles
Inspection after disassembly

Takeaway:
Ice Pad cause no interface degradation throughout the 2000 test cycles. 

 

Coupon thermal resistance change due to thermal cycling
 

 

Thermal interface quality degrades with increasing cycles for conventional TIMs:

  • After 2000 cycles the thermal resistance of grease is 2.6 times that of Ice Pad
  • After 2000 cycles the thermal resistance of PCM is 1.4 times that of Ice Pad
     

Using Ice Pad, customers are able to:

  • Remove heat effectively and reliably over time
  • Expect less de-rating of electronics over time
  • Build higher performance electronics that last longer
  • Generate less e-waste and be more sustainable

GPU cooling

Ice Pad enables better cooling for GPU

The challenge of GPU heat management

GPUs are incorporated by data centers to handle increasingly intensive workloads:

  • They are affected by large thermal variances during operation
  • Heat buildup reduces GPU’s performance, stability and lifespan
  • Reliability of data centers will be compromised
     

Meet Ice Pad

Ice Pad provides high thermal conductivity of a solid TIM and low thermal resistance of a liquid TIM, with reliable long-term performances and high volume manufacturability. For this study, we used IP90 with 2-sided assembly tack.

Carbice Ice Pad demonstrated immediate better cooling and long-term gains to GPU performance compared to POR Grease:

  • 2℃ cooler upon initial installation
  • > 6℃ cooler after extended use

Over time, grease pumps-out and develops dry-cracks, causing its thermal resistance to double after extended use. On the contrary, Carbice Ice Pad wets the interface even better with time and cycling.
 

Takeaway:
Ice Pad provides better lifetime cooling performance than grease.

 

Using Carbice Ice Pad, customers are able to:

  • Lower GPU temperature 
  • Boost GPU performance
  • Extend GPU lifespan 
  • Increase data center reliability
Carbice is nothing short of revolutionary and will completely disrupt thermal management in every industry.
