HP's new Neo (12W TDP) based microserver (with HW decoding)

Hi All I just thought I'd see what people thought of this new system from HP - it seems as though it meets the spec for what a lot of people here want to build - a low power, low noise server for media streaming. http://h10010.www1.hp.com/wwpc/us/en/sm/WF05a/15351-15351-4237916-4237918-4237917-42480...

Now what would make you write something so contentious? How would you show this? Because the situation in hand is related to 2 identical processors in like-for-like cases. The thermal diode is in the same location in both situations. You are right in saying that using the term "I suspect" is conten...

I'd suspect poor calibration of the thermal sensor (im guessing an AMD cpu? the P4s are usually a bit better) and/or different application (and effectiveness due to this) of the thermal compound

I no longer require the previously metioned produced - ROMTEC TRIOS - I can sell it if you are in the UK - would save you a fair packet as its pricey to get it in from the US. I would highly reccomend the product, especially since it has a fool proof design (cannot change while switched on)

im inclined to agree with you on all of those comments. i didn't atually notice the thermal peformance then, but if my memory serves me correctly to find the "balanced" temperature, you calculate ambient room temperature + ( power (in watts) x thermal resistance (C/KW) ) so its 23 + (80*0.33) = 49.4...

"Intel P4 Socket 423 &478" is all it says - you could always contact them. Remember it is listed underneath their "server/power" section, so it should be able to handle a fair whack. For £11 you cant go wrong!! its cheaper than most h/s and fans and by the looks of it, its much better quality than a...

remember that the power supplys are rated at 300/400/500 Watts MAX - This is not a continuously rated supply. They do not state the maximum continuous load. They generally over-rate much more on the cheaper power supplies. quality goes a long way with power supplies, although there are only a few co...

Well ArticSilver thinks that a fan on the heatsink helps to shorten the breakin period. I guess due to vibration but I could be wrong. The change that occurs during the break in period - the purpose of thermal paste is to maximise the thermal conductivity accross the surface of the cpu. There are m...

I think that any forum members that are associated with/work for/sell silent products have a mandatory distinction (perhaps having "TRADER" where 'silent apprentice' or 'admin' normally is, also a graphical avatar to distinguish them) also a rule which stops them from promoting their products too much
