I just switched from a globalwin FOP 38 w/ a 7000 RPM fan to a thermal right SK-6 w/Delta 60(7000) fan and i started using Arctic silverII, and my tempwent up to 46c from 44c (and im no even O/C yet). Did i do somthing wrong throw me a bone please?!?!?!?!?!:confused:

Not sure if I follow what your saying? If your saying there is only a 2c decrease in idle temp, that's not really bad. The big difference will be realized when you do actually start overclocking.
The copper of the SK6 will most surely outperform the FOP38 once you start raising voltage/multipler, etc. Could also be an issue of case ventalation. If your case in general runs hot, then your idle temps are not going to be drastically reduced by switching to a copper heatsink.
In fact, your general case ventation requirements increase when using copper. That copper sink becomes like a little oven inside your case. Copper pulls heat off the core faster, but it does not dissapate heat to the air as fast as alumnium, so proper case air flow is a must.
Hope this helps!

no my idle temp went up to 46c from 44c with the SK 6

Woops! Bad reading job on my part. Again...how is your case ventalation? Do you have at least 1 intake and 1 exahust fan? What size case?
The manufacturer have been slacking off with the SK6 so check if all the fins are soldered properly & the bottom is indeed flat. That is if you did not make a mistake mounting that hunk of copper;)
well I just put one in my system. My Idle temps went from 113 to 95. Make sure that you have it mounted right and that the fan is blowing the air toward the HS not sucking.

OH yeah I remember too that I still need to lap the bottom cuz it wasn't that smooth.

What you mean I gotta be careful how I mount a HS. I thought I could use duct tape or something. Man was I wrong. I was wondering why when my hs was at a angle my temps went up. Doh!

I have one exhaust fan and no place to mount an intake fan(yet) in a mid tower case (gateway) the fan is blowing on the hs (i even switched it to make sure and the temps went up alot) bottom is flat all the fins look good and it is monted nice and tight with a thin layer of Arctic silver II between the die and HS. What in your opinion is to high tempature wise? Maybe I'm just paraniod!!!:(
Maybe since the SK6 is a lot more efficient than your old HSF the air inside the case gets hotter than before & with no cool air coming in you would be in trouble. Take the side panels out see what happens. Remember that if you run cooler with the panels removed than you have to work on airflow thru the case. My system actually runs cooler with the panels in place.

Mine does too cause it creates a tunnel of air flowing between two 120's at 7v. I made a pseudo type duct that kinda focuses the air from one 120 onto the heat sink.

i also recently recieved my sk-6 and on my first install attemp, my temps went to 100c, and i fast turned it off, then i realized that i had to take the tape of the termal compound, then it worked, but im not seeing temps decrease like everyone said they would, and this fan is like listening to a miniature blow drying fan(Delta), one this this hsf abled me to do is overclock higher, but i still wanna get my temps down lower then 50c, maybe i'll get a water cooler.

Well I dont know what happened I OCed my FSB up to 140 And then ran toast for 10 minutes, the temp got up to 54C then i shut off toast and the temp dropped to and stabalized at 40C. I ran toast again and it got up to 48C and no higher. Is it possible that the arctic silver II had to set up???????????
Well my opinion is changing about the SK-6 if my comp keeps running like this. Give me your opinion.:D
BinarySuperman - No HSF will give you good temps if you keep the thermal crap that they apply at the factory even the plain white gunk will do better than that:rolleyes: Get yourself some ASII or whatever thermal compound that floats your boat.
Reverend - Did you do the test with the panels on or off?

ok, well IDLE temps are crap. The only temps that matter are load temps running something like toast or another program that loads the CPU. Both your idle temps are high for both heatsinks, especially the SK-6. What motherboard do you have and what program are you monitoring temps with? What CPU do you have? What are your ambient temps? Did you remove the thermal pad from the SK-6(don't know if it has one, if it did it will be a discolored area in the center of the heatsink bottom). If it does, applying thermal paste to the pad gives awful results. Artic Silver Temps will go down after it sets, but not by more than 2C or somewhere in there.
A lot of questions, but we will get a much better picture of the problem with this info.

Im running an elements 866as-r mobo with a 1.4 t-bird, room temp is 75F mobo temp is 30C the sk6 i didnt use the thermal pad just ASII. CPU temp is 41C idle and 48C loaded(now).
I'm using the sk-6 w/ ASII and it seems to be working quite well for me. I have a Duron 850 oc'd @ 1064, 1.85v. Cpu load temps using Toast are at 43c depending on ambient temperatures. I think you need to add some case fans to add to the performance of your sk-6. You can checkthe link below to see how my case is set up. Try playing around with some case fans to see which helps your cpu load temps the best.

This is what it looks like generally. The blue is a piece of cardboard that connects the two sides of the case so the air cannot escape out around the sides. It curves right into the HS supplying fresh air. I notice the temps go up a little when I take the side panel off casue then the air can escape out the side. It is simply yet effective as without it my temps really are not affected if I keep the panel on or off. With I see about 2 deg. C drop in CPU temps.

I have a 1.4 @ 1.538 with a hsf that came with the cpu. My load temp runs up to 125 F or so, when the room gets warm. I have the sides off of my box and a fan hanging on the side blowing in on the hsf (a fan for my fan?) on both of my 1.4's. Last night though, I had the window open and the room temp got down to about 60 F and the load temp went to 105 F.
When I put the sides back on those cases, the temps go up about 10 F, so I obviously don't have enough ventilation in my boxes, so I leave sides off.
On the 1.4 @1.4, I have a Dynatron copper hsf, SK-66, at least that's what the receipt says, but I can't find that model on any web site. It looks like the DY1206BH-625, but the fan runs 7000 to 7500 rpm. I used ASII paste. I can't tell that it's a whole lot better than the retail box fan that came with the other cpu. That cpu runs about 122 F load temp. And it's not o/c'ed.
Both boxed are running Folding@Home.
You're doing better than I am temp wise. So, I thought I'd give you these numbers for comparison.

so you guys think its worth buying artic silver, if so can you give me a good site to buy it, and which type sould i buy.
Just thought i'd throw this in here, my SK6 is working fine. I installed it last night and upped my OC from 900 @ 950 to 900 @ 1ghz (PS is to weak to go any higher :( ). Anyways it's almost 14degrees lower at max load than my CPU was with the factory HSF. oh yeah I'm using Arctic Aluminum as the paste.
and the sound of the 7000rpm fan isn't to bad if you listen to music/play games as your primary functions on the computer...gun shots and screams sorta tend to dull out the persistent whine of the fan.

Now that is more like it;) That is what a properly fitted copper HS will do for ya.
