NEw heatsink question

[tikki50]

I just bought a new heatsink sorry all you water coolers I just don’t have the cash for one of those right now. But I did get this setup:


119.0 CFM Vantec (Sunon) Tornado Fan 92 x 38 mm
Thermalright SP-94 Heatpipe Heatsink
They were out of artic silver 5 so I had to get 3 oh well.

Also finally ordered some round cables to clean up that mess inside!

2 sets of ide cables
1 floppy set.

Total 71.92 not bad with shipping.

Can't wait for this bad boy to show up at my door.


What kind of performance gain should I get. Right now my temps are cpu 36-38 idle 54-56 load. Yes it’s a bit high and that’s exactly why I purchased this heat sink. Should I shim the heat sink fan up some to remove the dead spot? Also should I make an air tube for it I heard those help a lot. I have a glass panel side so I cant mount a fan port on the side. I do have 2 80mm fans sucking air out they are very loud not sure of the brand. I have an extra 80mm and was thinking of mounting somewhere to help cool the GPU down, you can never have enough fans, LOL. Look at sig for vid card. Should I replace the stock fan with the 80mm I have laying around? Or just blast it with some more air? The other thing I could do with that fan is to use it for cooling my hard drives down would it be better suited for that? My SCSI drive gets pretty hot! 3 hard drives=HEAT.

My next step is to do some case mods. I plan on cutting out the finger protector areas around the fans. This should actually quite the fans a bit and increase CFM thank god I don’t have children.

Mine doesn’t have the fan port on the side its just solid.

I would say that you should get at least 3-5°C drop from whatever you had before with those parts, although I'm not sure what your last HSF was, so it's a little hard to tell. If it was the stock HS, you should see a large drop in temps.

1) Yes, you should put a shim/duct in between the HS and the fan, it does lower your temps a little.

2) I would also recommend the fan in the side panel to give some more air flowing in to your case. Two if you don't mind losing the view. I'm adding a 120mm fan to my window rather than put two 80's in there. Add a blowhole on top if you don't have one.

3) Organize your cables and cut out all of your case grills, front and back. That's good for at least a few °C's . Especially the cables... if you do a good job, some people have seen their load temps drop by 3-5°C. If you're into modding a little, you can cut holes in your mobo back-plate to wire cables behind the mobo, and by having holes around your cpu socket and NB, you can lower you temps by adding a fan hole to the side panel and putting a nice powerful fan on there.

Anyway, good choices on the parts... and good luck cooling!

thanks mtb I will try some of those mods. Not sure I want to start cutting holes in it just yet, its still new, man! Do they have duct or shim kits? I could probably make one. Is the purpose of these shims to just lift the fan off the heatsink some? That means it should be solid and not "legs" holding up the fan off the heatsink correct? I was thinking of adding an intake port for the cpu fan so it pulls air from directly outside of the case. I could use the lower back fan area and add fan port at the top pulling air out. Sounds like a fun pvc project, lol.

I expect you should see even a little more then a 3-5C drop if it was the stock HSF, probably even 7-8C if your lucky
to get rid if the deadspace on the heatsink, make a duct from the heatsink to the fan and your temps will drop a bit more as well, that mixed with the better cable management you should see some fine temps
Good Luck

 

[tikki50]

how thick should the duct be? Meaning how far should I raise the fan off the heatsink? 1" or two?

 

[[KX3]rAge]

2" should be plenty if you've got space, if not try 1.5"

 

[tikki50]

Yeah that heatsink is huge so that might limit some of my space.

Although the heatsink is large, it stays within the boundaries of the P4 retention bracket (which you will remove). When I had first purchased the SP94, I also paired it with a 92mm Tornado, but later switched to a TT Smart Case Fan 92mm for the sake of my hearing. I found that the Tornado did not have that much of an advantage over the Smart Case Fan, and was much too loud for my liking. Nonetheless, this is all my opinion.

You can use an old 92mm fan for a spacer..25mm = 1"...You have to take the motor out of the fan frame by cutting the motor struts away at the fan frame.
What is your system temp? See sig of rig below.. I use a fan frame for a spacer on my SP-94 HS..
