Swiftech/ what fan? or Alpha/ what fan?

[rlemieux]

I am thinking about getting a Swiftech for my 478. Along with it I need a fan. The obvious power choice is the Delta 80mm 80CFM or the Delta 80mm 68CFM. But I am also looking at the suron 80mm 50CFM and one by YS Tech that is 80mm 48.5CFM.

Now here are my question:
1. How much more cooling should I get with the 80CFM compared to the rest?
2. Is it a worth having a Delta 80CFM at 52DBs or would it not effect performance too much if I went with the YS Tech 48.5CFM at 37DB's?
3. If I got the 80CFM or 68CFM Delta and used the Swiftech rheostat what kind of performance and noise levels would I get?
4. Would I be better off using a Alpha Heatsink if I wanted a quieter system?
5. How much of a performance difference am I looking at between the Swiftech MCX478 and the Alpha PAL8942T with the same CFM fans attached?

I know this is alot of questions, but I am just trying to make a sound decision.

My main concern is performance, but if I am going to get something that is almost as good and drop half the noise I would rather go with that. As long as we are not talking about a huge jump in cooling performance.

Thanks.

I really don't know the answers to your questions, but I can tell you what i would do. Go with the Delta 80CFM fan and a rheostat. Also, use some type of filter over all of your case fans and case openings, like the small holes in the back of your case. The filters will block the noise, making the computer noticeably quieter. A thin foam filter will block noise well, and not block air too badly.

Let us know what you end up doing. I'm interested to see what kind of performance you get at lower RPMs.

They had a Socket 478 HSF roundup with the Swiftech MCX478 and Alpha PAL8942 with different fans. I think the article will answer most of your questions.

Hey man thinks that was very useful. The Pal actually performed better at lower rpm’s and it wasn’t that far off at higher rpm's. I would like to see more than one review comparing the two, because they sometime can very, but I really appreciate the link. It was the most helpful response you could have given. Thanks again!

here is an idea. get a piece of pexiglass and a heat gun and make yourself a adapter to use a 120mm on the alpha. by using 120mm 69cfm 35db fan you will keep airflow but will be almost silent. both panaflo and sunon make models in that range

You do not think that by modifying the design it will reduce performance? Also, if I get the alpha I do believe I am going to go with the 50CFM Suron or the 48.5CFM YS Tech. They both are between 39 and 40dbs.

Good choice with the 8045 and 50CFM Sunon! For the Swifty to work BETTER than the 8045 it needs the loud 68 or 80 CFM delta. The Alpha does VERY well with a slower speed fan. I tried a 50CFM Sunon on my MCX462 and the temps went up 8C!!!

does the swifttech use a 80mm fan?

 

[crose]

Yes, they both use 80mm fans.

BTW look at these tests done by Alpha. They have compared fans with varying CFMs on the PAL8942.

does the swifttech use a 80mm fan?

check out the review though, Swiftech performs better with high output fans, Alpha outperforms the Swiftech with lower ouput fans.

Also http://www.plycon.com offers a 80 to 120mm adapter for like 16 bucks.
