## Questions & Answers

**Q: I’m looking to cool a couple of thick film resistors that keep overheating. Can I cool more than one (2) with this heat sink?**
A: I would think so. It depends on how much power they are dissipating and how much airflow is on the heatsinc

**Q: Is this anodized?  Also what is the alloy?**
A: It's very shiny which might lead one to believe that it has been clear anodized because it doesn't have that dull grey look of raw aluminum that's been left out for a while.  I have no clue about the alloy.  The packaging says nothing about the finish or the alloy.

**Q: Can you make anodized 200 x 138 x 36mm block? Thanks.**
A: Hi
69x36mm HeatsinK, already all silver oxide item surface, you can use two side by side to dissipate heat for electronic products, thank you

**Q: What is the thermal resistance of this heat sink in the 400mm version?**
A: Short answer:  About 0.4 oC/W/16in (still air). For others who purchased a different length, they will need to adjust this number. 

From my review below, a more detailed answer: 

I found a dimensionally-similar (2.581" wide instead of 2.71", 1.340" tall instead of 1.41" tall) heat sink in an online AAvid catalog, model # 83220. The AAvid heatsink specs were 1.01 oC/W/3in (still air), so I'm expecting this heatsink could be 10% better (lower). Note that if you bought a length other than 3", the thermal resistance does not scale linearly with 1/Length, assuming a centrally located thermal point source. For the 15.75" length I'm using, the improvement is only a 50% reduction in thermal resistance. 

Also note that the thermal resistance decreases (improves) with moving air. While the documentation I found for the #83220 did not provide thermal resistance versus air flow, I found another AAvid catalog and heatsink #72070 (dimensions 3.008" wide, 1.02" tall, similar fin aspect ratio, 1.4 oC/W/3in) that provided a thermal performance versus airflow table; for a modest airflow (quiet muffin fan) of ~700 LFM, the thermal resistance drops by about another 70%. 

Net result, for the 15.75 inch length option, operating with 700 LFM forced air flow, is expected to be about (1oC/W/3in * 90% * 50% * 30%) = 0.14oC/W. My heat source is distributed along the 15.75" length, rather than being a point source in the center, so I expect the actual performance to be 2-3x better (lower resistance) than the above calculation.
