Thermalright SK-6 too loud! Need help!

[IBJanky]

I currently have an Athlon XP 1800+ in my setup with the Thermalright SK-6 with a LOUD 60mm fan (7,000+ rpms?)

What can I do to quiet it down? Get a new fan? Get a new HSF?

Any advice?

I've been looking to replace the fan with a Vantec Stealth 12 CFM 60mm. Will that be enough for the SK-6 and a stock Athlon XP 1800+? I'm NOT going to overclock my processor. I will keep it at stock speed.

My main concern is the noise, that's why I want to get rid of the loudass Delta fan on there now.

Thanks in advance.

Deltas are notoriusly loud.

I know that on an SK-7 or SLK-800 that an 80mm Vantec Stealth could probably easily cool a non-overclocked xp 1800+ but Im not sure on the 60mm version. The SK-6 is a great heatsink for its size. A new fan should be your only concern.

I'm not really looking to get a new HSF setup, maybe just the fan. I'm trying to keep costs at a minimum.

I'm an SK-6 owner who has used the 80 mm fan trick (you mount the fan at a 45 degree angle, such that the corners are being held down rather than the sides) and an adjustable fan (back in the day, the enermax adjustables were the thing to have). Works well for my P3 CuMine running at 1188 MHz. I can keep the CPU fan at like 2200 RPM and get the same temps I was getting with a 60 mm Panaflo H1A.

Using the 80mm fan on Sk-6 trick also, much more quiet than my 60mm.

how do u secure the corners of the 80mm fan?

the sk-6 uses these wire thingies to secure the 60mm, I dont see how I can use them to hold the 80mm fan

please explain

I'm using a 60-80mm fan adapter screwed between the fins, And a 80mm fan. It's big but it works great for me. I don't think I've ever used a 60mm fan on it, as I grew tired of the high-pitched whine of my TT volcano 6cu+ Delta 7000rpm fan long ago. The wires hold a 80mm fan on just fine! You gotta work to get em on though. A fan adapter is a bit more efficient. I don't remember the temps with/without cuz I didn't write them down, but it's a degree or 2.

I have almost the same Heatsink(6cu+) and changed the 60mm delta to a ThermalTake Smart Case Fan and used the 60-80mm Fan Adapter , sure made quite a difference especially as the fan speed increases as the temps of the cpu do .

 

[Blain]

This is a 92mm fan mounted on an SK6+, but you can mount an 80mm the same way. You'll have to bend the clip arms down a bit to make sure the fan is snug. But it's not hard to do at all.

 

[ChurchOfSubgenius]

I think the fan adapter would be the best way to do it (I currently use the same method Blain does) because using the 45° method loses a fair amount of your air passing on the sides of the HS.
They have a "bent" fan adapter over at SVC that would be ideal.

EDIT: I just hit up SVC for a cheapo 60-80mm adapter (sold out of the bent ones) a Zalman 2 speed fan and Ceramique HS goop for $13 shipped, not a bad deal.

 

[GAZZA]

Only trouble is the bigger the fan the less cooling your actually giving it due to the hub of the fan, if you take a look at blain's fan the hub is covering the most important part of the heatsink that requires cooling which is where the core of the cpu mates to the heatsink.

 

[NewbieCanadian]

Not if you're using a funnel adapter. By raising the fan an inch or so off the heatsink, you greatly reduce the 'dead spot' under the fan hub, as the air can circulate under the whole fan (and thus across the whole heatsink).

Swapped out the loud-as-hell 60mm fan from my (sigh) Thermaltake 6cu for a slower 80mm fan by this method, and now have identical chipset temps at half the noise.

If you consider the back pressure caused by the funnel, it's not that much of an improvement over the clipped 80mm to get an adapter.

 

[Elcs]

Excuse me for being abrupt but if you are so concerned about the dead-zone that the fan doesnt blow onto well, just use a TMD fan. Reduced dead-zone but then again, it is the most awkward size and shape imagineable.

 

[ChefJoe]

My SK-6 is currently running with a TMD fan on it. I threaded the clips through the holes on the 70mm fan and it holds pretty well. I think the clips are bending a bit, but I'm ok with that on the cheap SK-6.

 

[IBJanky]

I did the 80mm fan trick. It's so much quieter now.

Thanks a lot guys!

I've been looking to replace the fan with a Vantec Stealth 12 CFM 60mm.

12cfm is not nearly enough for anything, overclocked or not.

 

[elkinm]

I would recomend a 80 to 60 mm adapter to focus those few 12 CFM as much as possible, but that is almost nothing. I am sure you can find virtualy silent fans with twice the airflow and that would be better.

One thing though, would and 80mm with the 45 degree trick work better then a 60 mm. As in most cases alwhough an 80 mm moves more air the air velocity is lower so heat is moved away slower. So does the trick provide good performance with a regular, not loud fan compared to a not loud 60 mm?

Thanks
