CAK II or Heatpipe Coolermaster for 1900+? Pls respond fast.

[Emericana]

The reason i say pls respond fast is because i wanna order either one of these sometime tonight.

Listen all, i have a sk6 now and while it is great, it does not work with my 92mm adapter. Now i am sure there is a way to mod it, but it does not matter cause i am going to be building another pc for a friend soon so why not use the sk6 for that since i would need to purchase another hsf anyways. now that that is all over with, i have narrowed it down to two choices, the globalwin cak ii or the coolermaster heatpipe (forget the model number), which one will give me best cooling? they are both $30 at newegg.


btw, i am going to be using Artic Silver Three on the hs.

[Intraveinous]

I'd go with the HHC (Heatpipe) model... It's gotten some excellent reviews and is a great price for the performance... Post your results and let us know!
Peace
John

[JFettig]

yea iv heard a lot of good about the heatpipe! but you gotta make sure you lap it! its supozedly very bad on the bottom so it needs a lot of lapping...

[Emericana]

what does lap it mean?

EDIT: I ordered the Coolermaster from newegg along w/ a 92mm thermaltake 56cfm 35DBA Fan. I am gonna use the 60-92mm adapter because i do not wanna use the 38cfm delta which is 45dba.

Lap is to use sand paper to even out the bottom of your heatsink so that it s perfectly flat. Try starting with 300 grit and then move up to 600. You shouldn't need higher than that unless you want to but you could go all the way up to 2000 grit. When you are done you will be able to see a reflection if you go up to 2000.

[deez]

you must lap your HS on a perfectly flat surface such as glass or acrylic

[JFettig]

i use a mirror and that works great!

[Emericana]

wait i dont understand this. you say that you use sandpaper to rub the bottom of the hs until you can see a reflection, which i understand, but what is this with glass tables or a mirror or something? what does that have to do with anything?:confused:

[The Doors]

They are the flattest base possible to work on, so you'll get an absolutly flat HS base ;)

[Scottland]

btw.. just so you know... a mirror is just a piece of glass with a painted coating on the bottom surface...

[JFettig]

what i do,
i took some 220 grit sand paper taped it to my mirror around the edges of the sand paper and held the heatsink flat, and rubbed it.......
then i took 320 and did the same
600 800 1500

[bigggwilly]

He he... I always thought they looked similar... he he

[Emericana]

i went into my basement and this is what i found. I have a box of sheets of sandpaper that says "Fine- 150" on it and a Sanding Sponge which says fine/medium on it. Will either of these do the job? i am not going out to home depot to get five or six types of sandpaper. i have spent enough money on cooling for the system.

[The Doors]

I'm sorry Emericana, but I suppose that this is not the right sandpaper, you need wet/dry sandpaper, generally used to repair the cars body (sorry I dunno the translation :)) grain 600, 800 & 1500, and if you want a mirror finish well a 2000 grain too ;)

[Emericana]

what happens if i dont lap it then? i have artic silver 3 so would it really make a difference?

[JFettig]

oh itll work just fine without lapping as long as you arent gonna overclock to the extremes!

i just made myself a 60-80mm adapter! but my temps are up.... running at default 800tbird im runnin at 40c just using my computer
with my everflow off of a 6cu+ my temps were around 34c

[The Doors]

Yes, there is absolutly a difference in temps, but it's very difficult to say how many degree will drop the temp, coz depends by how much the HS bottom is flat, but for sure at the end of the lapping process will fit at the best possible, and AS III will help a lot too ;)

[Emericana]

well as stated in my sig, i got a unlocked 1900+ and i am going to be trying to hit 1.8ghz but i am not going to do a volt mod so that makes it at 1.85 volts. do you think i should lap it? how much $$$ does all of this sandpaper cost? will a home supply store like home depot have it or only a car store?

[Trieber]

I would say an auto store, but then again, most hardware\homesupply stores should have it.

About the sandpaper, can I just start with 2000, or should I start with 600 and work my way up?

Hmm, you should lap no matter what though from what I've heard...

[The Doors]

The sandpaper sheets, that I've got in a car shop, aren't expensive, I've spent no more of 5$, and you have to start with the bigger grain, 600, after 20-30min go with the 800 and only at the end with the 1500, for a mirror finish go with the 2000 too ;)

P.S. for the best results use the sanpaper sheet wet, and continue to add water during the process, if the sheet is too much dirty, well, no probs, put the sheet under the water flow, obviously without the glass or the mirror base :p

Theyre not that expensive. Home depot usually doesnt have higher than 800. You might have to go to Checker or Pep boys (Usually the 1500 and 2000 is what they use on cars inbetween paint jobs, or so im told)

I think it was like 4 bucks for the 1500 and 4 for the 2000. And it does make a diffrence. My roomate did this to his cak II and got Ibelive 4 or 5 degrees diffrence, My swiftec already had a flat base (Not shiny but no imperfections) So i skipped it. But most heatsinks you get unless they are machined perfectly come with a rough base. or at least imperfections.

Plus the sandpaper will last a while. I used like a sheet and a half on the 4 HSF ive used (Use wet dry. Just wash it off) and I still have like 3 1/2 sheets left. Plus if you go to home depot you can usually but the 600 and 800 for like 65C a sheet.

[Emericana]

ok... today i got my drivers licence!!!! and first thing i did was go over to home depot where i picke up some 220grit, 400grit, and 600grit, then i went to a car shop and bought some 800grit and 1500 grit.... should be pretty fun lapping :)

[Scottland]

LOL!!! Lapping.....Fun...

if you say so... lapping sucks but i always do

takes a couple hours.......so enjoy the arm craps :)

[Yodums]

Uhh make sure you wet the sandpaper before using it for 15mins or so.

Use glass. Remember to take the fan off if possible. Take dental floss and take the thin string and then tie the clips so your not standing that.

[jbell]

being a person who uses the ''heatpipe'' - I say get the heatpipe!!!!

I run 1.33G 266fsb stable at 1.5Ghz 300fsb and at 40C full load!!!

[Emericana]

well obviously i was joking about lapping bieng fun...

wait are you supposed to wet the sand paper and when it is wet lap it or are you supposed to wet the sand paper then let it dry and then lap it.... also, how do i know when to move up to a different grit sandpaper?

You usually just sand it til the paper is no longer sanding. wash it off then sand it (Wet is fine, you should have wet dry paper anyways.. right?)

Umm.. Just the feel. You just want to get rid of surface imperfections (Some people go for the mirror shine as well) so when it feels smooth just move to higher paper till its done no imperfections and feels very smooth to the touch.

[Emericana]

i got the heatpipe today... the odd thing is is that it is not really scratched up on the bottom. i took a few pictures on my dvcam to see if you guys think i need to lap it. it is smooth if you move your finger across the base but there are little lines and such on the base... the picutres are hhc001-1.jpg hhc001-2.jpg and hhc001-3.jpg what do you guys think?

On your final lap, use some ASIII as your lube. That'll work that stuff into the gaps. :)

I wouldn't really worry about a mirror finish, the main point of lapping is to get a flat surface.

[JFettig]

LAP AWAY!!!

it does need lapping because if there is any small eaven not seeable lines its gonna reduce performance greatly!

[Emericana]

YESSSSSSSSSSSSSSSSSSSS!!!!!!!!!!!!!!!!!!!!!

after 3 insanly fun hours i finished lapping the heatpipe! before is started it i could not see any reflection at all and now i can see nearly a perfect reflection! started at 200, then 400, then 600, then 800, and finally 1500 grit and it worked pretty good. when i was done i dumped rubbing alchlohal on the heatsink and right now it is drying. i will wait 15 minutes and then put the heatsink away for the night. tomorrow i will put some as3 on it and thell you guys the results.... btw i am going to be using it with a 92mm adapter and a 56cfm (only 35dba!) fan... cant wait to see those temps drop!

[JFettig]

if you have a delta, you should try that also! like a 60mm one...just to see the temp changes.....
like when i MADE my 80-60mm adapter my temps went up.......
but i had 4 less cfm wich shouldnt matter....

[UserName]

heat sinks are great, but they have a weakness.

more air wont cool the cpu better.

heat sinks work by boiling off a substance. once you get to that temp and the boiling starts, the cooling kicks in hard. But you get nothing below that temp. so you prolly will get the same temps with a smaller fan.

i could be all wrong about that in this case buts that's how they work.

[Emericana]

there is no way i am putting my 50cfm delta back on.... that is 54dba and it is the absolute most annoying noise i have ever heard. i value my ears.... since the thing is 56cfm and 92mm, it should cool at the same as like a 40cfm 60mm right? 40cfm is fine as you can get pretty decent overclocks w/ a 38cfm delta. i am not gonna volt mod my mobo or anything, just have it at 1.85... i am shooting my 1900+ for 11.5x157 which is 1805mhz. Since i have read about numerous people on the 8kha+ getting in the high 140's by just upping the FSB, i see no reason why i would not be able to get that by lowering the multiplyer and raisin the fsb.

i am also using asIII, and an aluminum case with good airflow and a bunch of fans so that should keep the cpu pretty cool.

[JFettig]

im jsut sayin you should try it and see what the temp diff is like only for an hr....you can wear earplugs or something...hehehe

but i was wondering about the temp diff...
cince with mine i got about 6c worse! with my 80mm fan vs my anoying everflow

[CrystalMethod]

The idea behind lapping, isn't to get a nice shiny mirror finish that you'll never see. It's to get the bottom of the heatsink as level as possible, and take out the machining marks left by the manufacturing process. The shiny mirror finish is just a an added bonus.

[Emericana]

OMFG right now i am typing this from my new PC w/ the Heatpipe installed and i am SOO happy i installed it w/ the 92mm! My pc is DEAD QUIET. I thought that it was so quiet that i had to open the case in order to check that the fans were on. Right now i get 42C full load and that is before the AS3 kicks in. I am guessing i will get around 35C full load once it does. Then i will raise the voltage to 1.85v, lower the mult to 11.5, and start ocin!
