Thermalright SLK-9xxU again.

edited January 2004 in Hardware
Now I am on the verge of ordering this copper monster.

Should I choose the 900U or the 947U?

The 900U is on sale for £30.7/$54/€43.7

The 947U costs £36.35/$64/51.74

I have read a couple of reviews, the two coolers are quite equal in terms of cooling.
But are there any differences in the mounting method or anything else?

Should I wait for the Thermalriht SP97 instead?

    Well, the 900A and the 900U are similar-- so similar that they should work well even if used on the "wrong" brand CPU, except for mounting hardware. The Intel CPUs were built to run stable at around 50 C. I would say save the extra money and stick with the 900U.

    But that is my opinion. Myself, will be getting a 900U for my P4 about the time I move to next P4 board generation. The 900A really rocks!

    One thing is to note that real fine fin spacing results in accumulation of dust real quick, and the 900A's spacing is about right. get dust in fins, the metal is insulated from airflow, poor airflow results and the metal holds more heat. So, hyperfine spacing of real thin fins will give more surface area, but narrower spaces allow for less air flow, and you get to a point where too little airflow through fins ends up resulting in less cooling per square inch of metal radiating area even without dust in between fins. The 900 has a good balance.

    Thanks
    Dust will not be a great issue.
    I have a filter mounted on my intake fan, and I have blocked a lot of holes taking in false air.

    I think I will order the SLK-900U then.
    I think the SP97 will be quite expensive over here, when it is introduced.
    The SP94 costs $83 at present.
    I suspect the SP97 to be introduced at a similar price.

    I would get the 947 just to be on the safe side. The 900 doesn't fit all motherboards well.

    I am in the position myself of needing to get a new HSF and was very seriouly looking at the SP-97 (there are a few places in the states that have them right now) since I am selling my SLK-900A to my brother. I had been looking at going water for some time and realized that If I had not got the last 3 HS's and misc cooling goodies I could be set with a nice W/C setup right now. So on that note I would recomend that you wait for the SP-97 as it is a very noticeable increase over the SLK-900/947 or wait to go water. I may even go to an old standby HSF till I get my W/C equipment and new case. That way I can have all my case mods done and W/C set to go so all I have to do is the normal installation of components. I hope my viewpoint helps.

    Interesting.
    I am a bit worried about the price of the SP97.
    It would be quite similar to the SP94 price I think.

    The 900U should fit my NF7-S.

    Dunno whether or not there is enough room to mount a passive Zalman NB cooler though?
  • EyesOnlyEyesOnly Sweden New

    There might not be regardless of which hs you use since the zalman is very large. Perhaps geeky can answer that question. As for the sp94-97 all i know is that it costs more, looks funny, and are supposed to give better temps. If the price isn't a problem then go for it. But there's nothing wrong with the 900 and even if it fits your mobo the sp97 might not due to the heatpipes.

    According to Thermalright the SP97 should fit my NF7-S.
    It is on their list of compatible motherboards.

    I'd buy the SLK900U, if it is cheaper than the 947U. AFAIK, the main difference between the 2 is the way the sides are cut for better clearance around the socket. They both perform similarly, within margin of error so as not to make a difference between them in cooling capacity either, from what I've read. I don't see any problems mounting a 900U on an NF7 board either as it has plenty of clearance around the socket. Also, if you would decide to sin later like me and build a Pee4 rig, you shouldn't have any clearance problems either with a 900U.

    I will say something about their mount though. I just bought a SLK800U and I found that their mounting system is harder to install than the mounts for the Swifty's or the Alpha 8045, but that X-member across the back of the board makes for a more secure mount that better distributes the hs weight across the mobo better. This would be important on a rig that is moved around a lot with all that heatsink weight hanging on the mobo.

    I didn't feel like checking their site but if it says it fits then go for it. Good points muddoctor.

    The 947u performs better than the 900u in all accounts. The 974u fits the NF7-s fine as well (It's what I have on mine).

    If you dont want to wait for the SP97, go for the 947u.

    Thanks again for the advice given.
    I am almost certain that I will buy a SLK-900U.

    I am not moving my computer a lot, but I would like the added safety.
    I wouldn't like a 500 gr. HS tumbling around in my case.

    Unfortunately I have to buy it myself.
    I didn't get one for christmas. ;)

    EDIT: I have found a review of SP97

    Now there is a pricetag on the SP97 in Denmark.
    The price is approx. £44/$79/€63.

    The price of the 900U and 947U are the same.
    900U £30.7/$54/€43.7
    947U £36.35/$64/51.74

    I have read a couple of reviews of the 900U and the 947U.
    According to the reviews the two HS are equal to eachother.
    The difference being one or two degress centigrade.
    It seems that the price of the SP97 is a bit too steep for my budget.

    I don't think you'd be disappointed with the 900u.

    Actually I will be purchasing a 947U instead.
    The 947U is available in a shop close to my location.
    This way I will not be paying for shipping.
    It is a bit more expensive than the price above.
    But the saved shipping makes up for it.

    Does the 947U need customized stand offs?
    I think I read that the 900U needed those on the NF7-S 2.0.

    The 947 is a better fit on most boards since it was designed to be more compatabile with more boards. I have a feeling that it will be replacing the 900.

    Uhm, I post this here, I hope I´m allowed sice I´m new here. :P
    Well this simple question; How did you guys mount you slk 900 on mthe nf7-s? :rolleyes: The standofs wont go through the board, they´r to wide.. :-/
    I´ve got the standard standofs, and I bought the coller for about a half year ago. (I had the ep-8rda3+, until it started to burn (I did´nt find a better way to spell that, I´m norwegian :wink: ),and today I got the nf7-s. :clap:
    So, sombody that can help me here?

    I had no problems with getting the standoffs through the holes on the mobo. The only thing I had to mess with was the mobo's standoff closest to the CPU, which I had to remove as it interfeared with the "X-Plate".

    Are you sure you have the correct standoffs? Oh, and welcome to SM!

    UM, ERR... For Athlon, A series is easiest to to mount on an Athlon XP supporting mobo, it locks to socket itself (Locks onto all three tangs on both sides of my socket). Thus, SLK-900A for Athlon, U for Pentium 4 is more common. Will leave it to others to explain how to adapt a U suffix SLK to an Athlon or Barton board...

    The "U" stands for Universal John. If a Athlon mobo has the 4 Holes, it should fit just fine.

    It is alright now, I just had to modify the standoffs a little. :)

    Thank you for the replys guys! :thumbsup:
