Swiftech 462A Results.

[Pat]

Just installed the cooler with a Paniflo 80mm 39cfm fan. My Asus Probe reads the same temps as my PEP 66 with a pair of Y/S 26cfm fans pushing & pulling. I'm running 43*C under load. Called Swiftech & they said that it should drop in the mid 30*C when I install their special 80mm 69cfm Delta fan running at 2/3 speed. I was worried that I never had the heatsink mounted properly. Guess I would fry the cpu if it was not mounted correctly.

So much for reviews! It sure is a lot quietier now, but not worth the addition 100 bucks.

This is exactly the kind of thing I've been going on and on about.

Don't believe everything that you read. Take everything with a grain of salt.

I'm sure the 462A is a great heatsink; probably even the best. However, at what point is a heatsink worth $80+? In my opinion, never! There's only so much that a heatsink is going to accomplish. Your PEP66 is a great heatsink. A lot of webmasters are doing people a disservice by boosting these outlandishly expensive cooling devices. To be honest, $30 is probably too much to spend on a heatsink.

If a person is really serious about overclocking a Socket A CPU there's only so much that cooling is going to accomplish. Of course, you must keep the CPU within a reasonable operating range, but spending hundreds of dollars to achieve a minimal difference in clock speed is a horrendous waste of money. Especially, when the top of the line Socket A CPU is just over $200.

Now, I realize that overclocking is a hobby, and there's a lot to be said for novelty. I myself enjoy tweaking my system quite a bit. Goodness knows I've spent a lot of time and money trying to get the most out of my computer.

I suppose the whole point of this is. Don't get your expectations too high anytime in overclocking. Inevitibly you'll be let down.

Pat, how much do you know about axial fan physics? This is not a slam, just an FYI. If you look at the actual airflow out of a conventional axial fan, it is not a straight "gush" of air. The air flies out in an ever increasing cone. The MC-462A needs the air driven straight down into it. The special delta fan that goes with it has airflow straightening vanes molded into the housing. They make the airflow more (not entirely) straight. They also lend to improving the performance in the presence of back pressure. Conventional axial fans deliver virtually no air flow when they encounter even a little resistance to the flow of air out of them. The best solution is a centrifugal fan aka cage blower aka squirrel cage fan. I've been looking for a long time for a small physical footprint cent. fan that runs on 12V. That would be the all time, best fan for heatsinks. They are very quiet for the volume of air they deliver relative to an axial fan. Different technology, different results.

Hoot,
Thanks for the info on the fan. I will post the results when I install the Swiftech Delta Fan next week. It is suppose to arrive Friday.

The only squirrel cage type fans that I have seen are the 80mm that suck up & discharge like a blower motor. They are rated at a low cfm. 2cooltek has them in stock.

The overall change right now is the noise factor. My system is so much quietier with the two Y/S 60mm 26cfm fans not in the system. I quess I would go nuts with a Delta 60mm 38cfm within my case.

I'm not slamming Swiftech, but sure makes a person wonder about the reveiw process. I know all of the tests were run with the 462A using the special Delta Fan, but I never would have thought that a fan could make that much differents on this massive heatsink.

Thanks,

Pat

A while back, I posted a gag post with a picture of a huge Fasco centrifugal blower 1A @ 120VAC mounted on my case, blowing down onto my FOP heatsink. I think the title was "You too can own a .2C/W HSF". I actually ran the blower and it actually delivered .2C/W performance. At 186CFM, the motor was quiet, but the noise from the air blast gave me a headache. Was like sticking your head out a car window going 60 MPH. The point being, even an average heatsink will yield good performance with enough airflow. However, to demonstrate the performance of just the heatsink part of the MC-462A, I ran my 600 Duron at 600, with the core voltage as low as it would go and run stable. Get this. Without any fan blowing on the MC-462A heatsink, case open, case fans off, it held the 600 Duron at 42C in a room at 20C, running Prime95 torture! Stricly convective cooling.
Yes, I do lots of strange testing

the silverado has two small squirrel cage fans and a silver slug that meets the core....I beleive it beats the Swiftech462 and was the quietest as well. Wonder how you get a hold of one of those puppies.

Say, where can/do we order those Delta fans that gazillions of people are talking about? It seems to me like it is the best fan that may turn a so-so heatsink into a very good or even excellent one. My order of a GW WBK38 is on its way and I may order this Delta fan to replace the one on WBK38. What do you guys think?

 

[Tachyon]

If you can take the noise the Delta fans do decrease temperatures. Like everything else in life it's a trade-off

The Delta Fan that is used on the 462A is a 80mm & 38mm thick. Your standard 60mm & 80mm fans are 25mm thick. This fan pushes 69cfm at full blast with a dba of 48. The dba of a 80mm Hs fan is a different sound than the 60mm 38cfm Delta rated at the same dba. Less rpm whine

Less whine but more growl, eh?

My Swiftech MC462B will not fit onto my Asus A7M266 mb because of the extra capacitor as compared to an A7V. Anyone tried this?

 

[spyke]

anyone know where to buy the delta 80mm 69 cfm fan by itself?

 

[Hoot]

I'm not sure where, but my guess is that demand is way ahead of supply on that model. Swiftech is held up shipping complet MC-462A units because of the fans being backordered. Delta has the specs for it on the Web site. Perhaps they have a rep list there.

Just removed the cooper shim. Room Temp is now 70*f, Case Temp is 73*F, M/B Temp is 75*F, & CPU Temp is 98*F with Delta Fan running at the lowest speed. I do not have any cooling software installed yet.

Swiftech told me that I could get into the mid 30's running the fan at 2/3 speed. They are close!

So, you got the rheostat? Glad to hear it is working out for you Pat.

I spent an entire day looking for a place that sold Delta fans of any size and could not find anyone that did. I also checked the Delta web site and could not even find a list of distributors. If anyone comes across a place that sells Delta fans by themselves please let us know.

after reading the review (either on anadtech or tom's hardware guide, I don't remember which) I looked to see if anyone sold them. I finally found noise control's web sit and had to use babblefish to view it (its in german I think). And it seems this is one instance where the americans are the unlucky ones. There currently are no distributors in the US. If you find one let me know.
