Cool Hardwarez has written a review for the Power Cooler PCH141 Heatsink, heres a snippit:

    "Previously I have tested another cooler from Power Cooler but of a different model, which is the PCH113.. I was quite disappointed with "orb" looking coolers because even though they are so "beautifully" made, the performance is way lacking. Anyhow, I hereby bring to you a review on their PCH141 which is gratefully not another "orb"!"
