Phenom quad/MB chipset cooling
Found some old tiny fans, not much bigger than between an inch, less
than two. Smaller than 486/586 fans, not sure where they came from. Took the two PCI cards out and got lucky by swapping the longer of the two, over the MB chipset, for a shorter PCI HD controller. Then, the fan fit over the MB chipset;- secured at a slight angle with one screw, airflow flow going down. Even had a handy empty SYS Fan MB header and didn't have to splice up something. Maybe 10F cooler offhand. Couldn't wait until summer as the new 2.2 Phenom CPU I swapped in to replace a dual 3Ghz, though only rated 6watts higher -- it's really bumping up the temps. Weather's still relatively cool and ambient 70 degrees, MB chipset temps were already rising to 125F (CPU 110). Not exactly sure what's going on, but also changed sides to the large fan on the heatwick's CPU cooler fins, moved it opposite and closest to a PS fan facing into the case. Both CPU dropped maybe 5 or 10 degrees, averaged/loaded, as well same for the MB chipset (w/ fan installed). I've run computer chips at 125F before, but I really don't like it and prefer things under that. Well under, although 110-120F I can live with;- 130F and I get hot about not especially trusting potentially a problematic situation escalating into a faulty computer. (I've had it five years and want to keep another five if only on principle.) Suspect Speedfan's report of the MB and an AUX, running close but not exactly lockstep for high temps are both the MB, with the AUX being a VID compliment to chipset(s) -- as both effectively under the same aluminum heatsink prettily labeled Gigabyte. Heh - also found a couple in my box of "leftovers" 2-1/2" 9-bladed 586 type fans. High quality. We, me and Gigabyte, with go another round if need be with the summer approaching. |

The fan is probably a 40mm. They come out of disk enclosures. I've replaced a few from disk enclosures. When I did a Northbridge heatsink, I got a reduction in surface temperature from 75C to 37C. The surface temperature was checked with a digital thermometer. My fan was a Ceradyne 6000 RPM fan. It gives the fan a tiny bit of CFMs but it helped a bit. The purpose of adding this, is the motherboard was part of an all-in-one computer for someone else. And the cooling was poorly designed. So I "fixed" it. If you want more cooling power, find a "concentrator". They used to sell plastic funnel-shaped items for computers, which convert the airstream from a larger fan, to fit into a smaller space. Kind of a plenum with concentration properties. Then, you can use a slightly larger fan, a fan which is thicker, and the fan can create a better static pressure level. That may give you more than a 10F improvement. The first item for sale here, is a 60mm to 40mm fan duct. http://www.frozencpu.com/cat/l3/g47/...cts-Page1.html Then you can put a 60x60x25mm fan on top. http://www.circuittest.com/cfa126025...-60mm-fan.html At one time these ducts were quite common. And cheaper than this one... Since they've fallen out of fashion, you can't find them quite as easily now. I've made my own fan adapters/ducts on occasion, as I have a bit of sheet metal in my basement for projects like this. http://arstechnica.com/civis/viewtopic.php?t=1053725 Paul |

I've made my own fan adapters/ducts on occasion, as I have a bit of sheet metal in my basement for projects like this. Amen. And, I've got them, too - concentrators. Well, one, albeit larger and CPU oriented. (Also found an all solid brass squirrel cage. Probably a $30/40 CPU cooler setup, before efficiently oversized heatpipes and wicking became what they are. Now, a hunk of brass, just a thing of beauty stuck in my box of prototypical "better rat-traps.") It's all boxed stuff, some saved from just before that Orleans single core CPU I first bought with this Gigabyte MB. Whatever I was running then in AMD (Athlon) flavors. That little HD enclosure fan, though, has given a better handle and indication to the problem. MB support chipsets -really- ought not be hitting 130F, and that new Phenom strongly indicates it's intending only to aggravate the situation. Oh, well;- getting up to 65F this morning inside, 60 outside. Nice and cool (for predominately a summer oriented climate, here, that's long and decidedly hot.) Time to fire up the Chrome Peacock - a one-armed La Pavoni espresso maker with a manometer. Cheers!, have a nice day. |

Altogether effectively an unreviewed unit in terms of longevity (maybe, only recently released). Not something I usually do. Thing that sold me is the warantee is 3yrs, for the same price positioning, over most available HDs with only 2yrs in a similar product lineup. It's a video surveillance HDD.
