Help! It sounds like an airplane!

[mrilock]

Hey guys,

Some of you might know I just put on a new Pal8045 with a Sunon 50cfm fan. I was getting idle 51, load 59 on my cpu, not great, but better than before.
I probably need to reapply my arctic silver II and do some other stuff to the actual contact between hsf and cpu, but I'm not concerned about that right now.

I'm concerned because I flipped my fan (so that it blows into the heatsink) and it sounds like an airplane taking off. I was worried that maybe it was just because of vibration, but should I just turn it around again? My temps are better this way, but I can NOT stand the noise. I actually have to turn up my speakers to hear music over the noise now.

You have a few options...

1. Put rubber spacers between the fan and the heatsink (cuts down on vibration). Cost: <$1

2. Put a rheostat on the fan so you can limit its voltage. Cost: <$5

3. Get a different hsf combination. The Glaciator (I and II) are supposedly the best out there for noise/performance ratio. I believe the Glac II is .16 C/W, which is outstanding for aircooling. Cost: ~$35

4. If you're feeling daring and have some extra cash, go for watercooling. I'm using a watercooling rig from Koolance (the new rig, not the old one) and it's quiet, not to mention extremely effective. Watercooling kits are available from Aquastealth, BeCooling, Dangerden, Koolance and many others. Cost: $100-250

Yes, if noise gets you then water is the only way.

Amedeo602, couldnt have said it any better myself.

I would advise changing your hsf. Those temps are really bad for what you have. If you go really extreme, say an SK6 or a MC462 you will be able to run a lower rated fan to get those same temps atm.

The SK6 fan clip design is excellent as it almost completely erradicates vibration. Vibration accounts for only about 20% of the noise of the fan but it is definately an improvement. I have a TE w/ same delta, but the fan on that sounds a lot louder.

You could also get a fan adapter, and a bigger fan that moves just as much air as the smaller fan, but it doesn't make so much noise.

If you go for water cooling, check out bong coolers (http://www.overclockers.com/articles389/). They're totally customizable and they're cheaper and more effective than expensive radiators.

Walter, that doesn't always work. Results with fan adaptors are normally quite bad. I upgraded to a 80mm 68cfm Delta Screamer. Only saw a 3C temperature drop. Normally, the higher temps are caused by inadequate heatsinks.

The reason 80mm fans dont work so well is that they dont 'blast' the heatsink as hard as the 60mm fans. More 'blast' forces heat to dissipate from the heatsink. CFM means nothing if the force on the heatsink is low. The 60mm delta has more force than an 80mm due to its steep fins and high rpms.

I would stick with the 60mm fans UNLESS the heatsink is 80mm. An 80mm fan is essential then.

Watercooling can cost even cheaper. For me it will go up to about 50 dollars Canadian. (30 dollars american) The only real pain in the butt is the water block. But either I'm egtting one made up for me, or I'm getting one sent to me free courtousy of some friends

I think I screwed up the fan. hehe woops.

by getting my fingers caught in the blades a few too many times, I think I did something. It isn't loud because of the air being pushed, but a high-pitched whine... I could imagine this being the "scream" you guys associate with "screamer" fans. Not being too familiar with fans, I'll just have to guess.

I may be able to get a free replacement. I was thinking about getting a lower output model, as right now there is so much air pressure on the heatsink that it keeps bouncing back.

I'm also thinking about taking an air conditioning duct and using it to suck air from the outside to my computer during these winter months. It is so dry here that I'm not too worried about condensation. This way I could get a pretty quiet fan on my heatsink and on the case. What temps would I have to worry about in terms of condensation?

Hey, frodo, sounds like you're onto something. How can you get a decent watercooling system for a measly $30 (US)? My pump cost twice that, not to mention my block and the parts for my bong cooler. Do you already have some stuff? If you don't, and if the part names aren't familiar, I might worry about getting a POS in there somewhere. Otherwise, I might worry about envious OCers TPing my house.
How can you do anything for $30?

That's news to me... Well, I once again gained some knowledge! :)

Thanks for the info Pitspawn!

And you didn't even have to fry a chip to do it!

[Wega!]

Yeah, lucky me :D

[Christoph]

Not so lucky me. Don't try dropping an HSF on your CPU. It doesn't help anything.
