Yea I got some ideas in that regard. Hopefully I can get my hands on more 478 stock coolers. I will test the one I have with a 3.4 GHz P4 and see what the temperatures will be like.

I was thinking more of a review video scenario! 😉

Yes - That would be very cool!

[edit] No pun intended.

115x stock coolers do not fit 775 boards, but some 115x boards will take a 775 cooler.

Intel uses several OEMs for the fans, with varying quality. Some seize over the years, some just keep on going.

two weeks ago a friend came by to my house with a 1155 board (a Giga GA-B75-D3H, known for a myriad of problems, probably due to poor power circuitry/VRM) that he managed to stuck a 775 cooler (from a Core 2 Quad Q9xxx) into it. I sold him a motherboard since his was dead and tried to fit the cooler twice before noticing he had a wrong cooler into it. Picked up a 775 motherboard to see if it would fit and it was spot on - wondered how much pressure he exerted into fitting that into his old motherboard. The holes were off for a good 4-6mm.

@topic: I have a C2Q 6600 that came with a tall heatsink, copper core and a paltry .20A fan. Replaced it with a Core 2 Duo HSF, this one is a bit taller, fully aluminum and have a .26A fan - around 12ºC drop. This 775 HSF i mentioned before is pretty small, but features a copper core and .60A fan.

Some newer boards did have mounting holes for 775, the advertised that feature, backwards-cooler compatibility. But yea, the newer sockets are spaced out more. On modern coolers that support multiple sockets, 775 position is more inwards compared to 1156 and all the others.

Something related to this project: Anyone know a good source of high performance / high airflow / RPM 80 mm coolers?

I found some on eBay China with 4000 rpm, but I have one fan that came with a Thermaltake Vulcano 7 that does 6000! What I'm seeing in the shops are all quiet models with around 2000 or less.

Thermaltakes from Socket A era are pretty awesome - they can move massive amount of air. For newer fans, check their static pressure too. Don't remember the URL but there were a site that calculated the amount of airflow from some info you feeded into it.

GlobalWin and the biggest, loudest Delta fan was the brute force Socket A cooling solution. Thermalright or Zalman was more about finesse. Thermaltake was a step down from these guys.

Came across a few S775 coolers.

The left one is from a Pentium D 805 rated at 85W. Surprisingly no copper core, but the fan has a higher current rating.

The one on the right came with a Core 2 Duo E4400 rated at 65W.

No picture, but I also came across a Pentium D 805 rated at 95W. That cooler looks like these two, but it has a copper core.

Haven't gotten around to doing any decent testing yet, just collecting coolers whenever an opportunity present itself 😁
