OK guys it seems it's pretty much confirmed. The HIS IceQ 5670, at least the 512 MB model, idles at 600 MHz
instead of the usual 157 MHz
. In the IceQ review they say it idles at 157 MHz in the text, but it's clearly a typo cause they obviously copy/pasted the text from the other 5670 review.
Also, see the review here at Newegg
(thanks klillevo), and the manufacturer's response that seems to imply it's by design:
Cons: 2/3 professional reviews show idle power consumption of this card >10W higher than that of cards based on the reference design (that's almost twice as much). The 3rd reviewer propably didn't bother to rerun the power tests assuming the numbers would be the same as in the previous 5670 revew from the same site, but their temperature numbers look suspicious and confirm the hypothesis.
Thank you for your valuable feedback.
The average power consumption of HIS 5670 IceQ is 24W in static windows and 69W in 3D Mark intensive test. It's only slightly higher than the reference design power consumption.
I hope the information will be useful to you. Please feel free to contact us again if you have further questions.
Again, thank you for support on HIS products.

Idle power consumption for the 5670 should be 14 W.
Maybe you guys that bought these cards and are having this problem could post reviews on Newegg, the manufacturer seems to be listening. I've had at least one positive encounter with a manufacturer via a Newegg review. Those reviews probably get much more exposure than these threads.
