Cooling question

I have a simple/complex question for the forum.....

I have a Antec 840 case and would like to get some opinions on the best cooling solution..

Have I gone too far, not far enough, or maybe just need better fans?

Front (blowing in)

2 x 80mm Antec (pretty low RPM, don't know the CFM)
1 x 90mm Antec (again low rpm, haven't a clue on the CFM)

Side blow hole (should it blow in or out?)

1 x 90mm Antec

Top mounted blow hole (Blowing out)

1 x 90mm Enermax 2300 rpm, at about 50 CFM

Back panel fans (blowing out)

2 x 80mm Antec fans

I have a Vantec 6035D CPU cooler hooked to a Rheostat baybus
(RPM range on the rheostat is from 4300 to 7200 on the Delta)

Currently my temps are a little higher than I would like and am going to be doing some upgrades next week.. Any advise would be great!

MB temp is around 26 to 28 C (idle vs. load)
My cpu temp is from 38 to 44 C (idle vs. load)

I am looking to have the case maybe 2 to 4 C lower, but am more concerned with the HSF. I've went through 2 of these Vantecs ( the first one had a horrible base, so in the process of lapping it, one of the cheap metal clips that holds the fan mount to the base snapped off!! I was able to have it replaced, and the second one wasn't any better. I just buffed it with some artic silver 2.)


Thanks again!

Youve got more fans than robbie williams

You probably just need a better CPU cooler.

What to buy depends on how much you want to spend.

For cheap but good then get the taisol 760

For medium cost get a sK6

For high cost get a big fat swiftech.

Thanks Holst!

That was what I was thinking too....My only concern is that I'll end up with another copper heatsink that will need the base lapped....I've been looking at the new Alpha and Swiftech, but have concerns about the Thermalright.. Most of the reviews of the thermalright say that the performance is great, but the heatsink needs lapping......Have any personal experience with this? I don't really want to spend $35 on something that will take a few hours of elbow grease to clean up when I can spend just a little more on a finished product (I've worked with Alpha and Swiftech coolers on friends machines and know they are quality)

Thanks again!

Ive also heard the same things about the SK6.
Now whey are very populat quality controll seems to have dropped a bit.

Lapping a heatsink is very easy though.
And its easy to buy the materials required.

I lapped my taisol760 having done nothing like that before and got very good results.

There is probably a guide on a affiliates site, if not ill give you a quick run down here.

It all depends on how much extra a swiftech will cost you and if you think its worth spending the extra.

Plus once you have the stuff for lapping, you can keep it for future use.

I think Holst has the right idea, but didn’t you say you have the stuff already, so its just a case of not wanting to do the job, if that is the case then it is worth noting that most heat sinks will benefit from a good hand lapping with a high grit paper, even if thy look really flat.

Kplonk,

It's not a issue of not wanting to do the job.. I have no problems putting a finishing touch on a already good job, but in my experiences I've had to completely refinish the surface. On the Vantec's, I had to take almost a mm off the bottom and spent 4 or 5 hours making it clean and even.. Both of the HSF's I received were uneven and looked like a HSF that was not quite finished..I think that's too much work to ask of a customer. I've only seen good things about the SK-6, but am unwilling to pay $35 for it if I have to give 5 hours of my time for a good contact surface...I guess I'm just paranoid, and should go with a Alpha or Swiftech...

Thanks for your help

5 hours !!!!!

Either your being very carefull or your not using agresseive enough paper.

Whylst building my watercooling block I had to lapp the copper bar stock. This had very deep scars in it from when it was made.

By using 200grit paper to start with I took 2mm off the base in a few minutes.
This left a poor finish but it was at least flat.

Doing the same on 800 grit wet and dry would have taken hours.

I lapped it to a mirror finish within 30-45 minutes.

Also use brand new wet and dry as it wears out quick when lapping a large copper block.

Yep 5 hours!

I was using pretty agressive wet/dry paper ( I think 200 or 300) to start, and the copper was so soft that it kept getting imperfections. I finished it off using 1000 and 2000 paper (left a sweet finish after all that damn work!) .Guess i'm a little of a freak about keeping things perfectly flat!! I never thought that i'd become a electrician AND a metalworker when I started building computers 10 years ago! I just ordered both of my top HSF's.. The Swiftech MCXC370 AND the Thermalright SK-6 along with a week 46 XP1600..I just broke down and decided that since i'm building a new comp, it would be best to get a new one for each machine...

BTW..... I'm now using a IWILL XP333 on a unlocked 1.4.....Very nice MB. Up to 180 FSB with Crucial PC2100.....Sweet!!

I appreciate your wanting to help, and not to crack like most other places!

Thanks again for your help!

by the way Holst,

I don't know if you're a F1 fan or not, but just in case, MONTOYA RULES!
