I'm a believer now.

[mrscintilla]

Unbeliievable.

Before: lian-li pc50. 36C/41C idle (cpu/motherboard) Noisy like hell.

Now: antec slk3000b 29C/27C idle (cpu/motherboard) Quiet as amouse.

It took a front 80mm fan to achieve that incredbly satisfying temp. W/o the front, w/ only the rea fan, it gets as high as 31/39.

What is so unbelievable about it? The Antec thermal engineering for the 3000 absolutely stomps the PC-50. That 3000 you have will even outcool their $200+ models. Lian-Li should take a few pointers from Antec, not only in how to cool their enclosures, but to narrow the price/performance ratio. There are simply too many flaws with their current cases to make them attractive to me....

I agree. it's too bad they look so damn good.

Like my Wavemaster for example... it really does suck, but at the same time, the incredible look of the case made me buy it anyways, and I love it... and while the cooling is better than I thought, my Compucase 6A19 (same as that Antec, and I do mean literally the same) cools incredibly well, while boasting the lowest noise possible. :thumbsup:

One small correction, Antec purchases the basic chassis from HEC/Compucase so it's them you should thank for the nice design.

I have a 3700AMB, wich is not TAC compliant, but I'll be modding it and adding my own air duct on the side panel. If I get it right, I might be able to drop about 6-9ºC of the CPU.

I'm running an incredibly quiet system now. I'm testing some Vantec Stealth fans at 7v, and I can't hear the computer from 1 meter away. I'm very happy with it.

BTW, what CPU do you have? 29ºC idle?!? Wow... I'm lucky if I get my 3G Prescott to idle at less than 40C.

 

[charlietee]

With Prescotts the only way to fly is to cut a hole for a 120m/m fan inside the case on the right side and cut out a square so the side will go back on.

I do this with all my Prescott builds...I have a Northwood with the cap removed and one of the temp probes off of a Lian-Li T4 taped close to the core...Inside case temp will be 24 degrees and 26, 27 degrees for the CPU idling.

And for hot rodding Prescotts having a 120m/m fan blowing on the backside of the CPU socket and northbridge is easily the best way to drop the temps dramatically.

Here is a pic If you notice the temps it is 25 degrees inside the case and the temp for the CPU is 33 degrees...That is after just starting it up...After 2 or 3 minutes the temp drops to 2 or 3 degrees above the temp inside the case.

If you have a Prescott and you want to hot rod it on air this is the way to fly.

 

[Zucarita9000]

That looks pretty cool. I'll try with an air duct first, since I don't want another fan inside my case. I've read that air ducts dramatically decrease CPU temps, of course, only if the air in the room is cool enough.

The Rig is an Athlon64 3000. I just OCed it to 2300mhz from its stock 1800mhz. The idl temp is now about 35C. Still quiet as a mouse. WInnie is the way to go.

 

[shabby]

Is that front door on the 3000b removeable? I have a fan controller and the knobs stick out around a 1/3rd of an inch, would the door clear them by any chance?

BTW, I see your hard drives are at 25C... how did you do that? Are they inside hard drive cooler bays?

Mine have a 120mm fan (intake) blowing direclty at them, and they're always at 33-34C.

mine have no fans blowing directly on them and my hdd temps stay between 25C-28C under loaded conditions (video encoding)

 

[charlietee]

Actually the one marked HDD is not mounted to anything....It is just sitting close to the top of the case to measure temps inside the case.

The other one is however mounted right next to the core like you would on a AMD processor...Heat Spreader cap has been removed from the P4 Northwood.

I do not remember what the HDD temps are but I will check it out later tonight and post back.

Oh...By the way any suggestions on the optimal location to mount the temp probe on the hard drive ???

 

[kt]

Mind telling me what you have to accomplish that? I have the same case, but my cpu/mobo temps are no where near that numbers. AMD or Intel setup?

Simple answer is that different motherboards report temperatures differently so there's no way to compare.

I agree. it's too bad [Lian Li's] look so damn good.

Beautiful cases, beautiful women.

Sigh. Computers really do parallel life.

 

[charlietee]

"Mind telling me what you have to accomplish that? I have the same case, but my cpu/mobo temps are no where near that numbers. AMD or Intel setup?"

My set up is a Antec PlusView that I have modded to accept 2 92m/m fans up front instead of the 2 80's...A 92m/m blow hole, three UV reactive Antecs, 1 in the door and 2 in the rear with the grills removed...And of course the 120m/m fan mounted to the motherboard tray...All of the fans are 7 volted except the 120 which is 12 volted.

It is a Intel 3.0GHz Northwood that the heat spreader cap has been removed...I will post some pictures later today...With the 3000 I put the 92m/m blow hole, the 120m/m on the right side that blows on the backside of the motherboard and cut the stock grills out.

Very effective...The 120m/m on the right side of the case blowing on the back of the motherboard is really the trick...Great case...I also have some pictures of a SLK3700 BQE that I will post to show how I go about cutting the grills out...No dremel...Just a pair of side cutter pliers and a flat bastard file.

And I agree with Nessism...Motherboard Monitor and some of the temperature monitoring programs that come with certain motherboards are just stuck on stupid...I know the Abit IC7 Max II Advance on my rig is totally wrong...Not even close...And to top it off they cannot fix it with BIOS revisions...I love the Lian-Li T-4's anyway...Put them in everything I build...Battery life sucks but for 20 bucks they look good and they work.

I just got a 3.4ghz preshott and ASUS motherboard, very interested in seeing any pics about installing the 120mm fans on the backside of the motherboard/case, and any links relating to this job. also can you let us know what tools you used so you didn't mess up the metal real bad?

my door clears the fan controller nobs on my case, there is close to an inch of room on mine

 

[charlietee]

I can post some pictures later today...My friend is messing with his ftp site and I dont want to upload any pics right now.

On the tool end of it I use a hole saw to cut the motherboard tray and a jig saw to cut the square out on the side cover...Since the hole is not seen you can use a jig saw for cutting the hole out also.

Just talked to Jason and he told me the coast was clear...Give me a couple of hours to size all this business and I will post the pics.

 

[charlietee]

This first pic shows the fan mounted to a Antec PlusView1000AMG...Try to place the fan where the motherboard stand off's will not be cut out...You can see the brass stand off's in the pic...A cd or dvd is the perfect size if you are going to cut out the circle with a jig saw...I try to place the fan where it will blow on the backside of the CPU socket and the northbridge.

Pic

These second two pics give you an idea what you end up with.

Pic 2

Pic 3

When cutting out the square for the side panel, I take masking tape and tape the entire side panel...Horizontially and vertically...This keeps you from scratching the finish...When cutting the circle inside the case this is optional...If I did not have a hole saw you can bet I would tape it up also...

This mod will drop your system temps better than anything I have tried...And believe me I have tried every trick in the book...Have hit 4GHz with acceptable temps on several DO stepping Prescotts in cases with this mod...7 case fans but the 120 on the side is where the most good is accomplised.

Cutting the fan grills out is another easy way to drop noise levels...I will post some pics this evening on how to do this with the pliers and a file with excellent results...I get much better results using this method versus busting out the dremel.

 

[charlietee]

"Is that front door on the 3000b removeable? I have a fan controller and the knobs stick out around a 1/3rd of an inch, would the door clear them by any chance?"

Yes you can remove the door...But most fan contoller knobs fit behind the door...I always take the door off of mine...Flimsy, easy to break and nothing like having your DVD burner sitting there making all kinds of unsavory racket when it opens with the door closed.

Uggghhhh !!!!!! Man I just cannot remeber the trick and cannot get ahold of Jason right now...I'll be back !!!!!

Probably named them wrong or something.

Working now.

On the overclocking Prescotts I have personally found out that Intel boards that have 865 chipsets are not up to reliable overclocking...If you want it to live you really need a board with the 875 chipset.

cool, I am using the LGA775 socket T 3.4ghz P4 550 with a ASUS P5GD2 premium motherboard with 915P chipset (asus is made for overclocking), the ASUS mb has the stackcool technology to try to even out heat buildup, coupled with the 120mm blowing on the back of it, it should be very cool

I appretiate the pics, I have a crappy case I am going to try these mods on, it only has 80mm fans, then once I do it I will buy a better case with 120mm fans like the antec super lan boy and mod that

thanks for all the info and any more pics would be appreciated

 

[charlietee]

More pics ??? Sure not a problem...If my writing skills were not so pitiful I would post a thread showing step by step how to go about cutting grills out and mounting 92m/m fans in the PlusView style cases...Cheiftech, Antec, Thermaltake...Bunch of cases out there that would benifit from these easy case mods.

I have literally hundreds of pics with the intention of a noob guide to cheap case mod's with an absolute minimum of tools.

Have to go borrow some memory from a buddy so I can get them off the hard drive in that systm...Sold the last of my DDR to JPSJPS.

Will be selling the case with a 350watt Fortron power supply...Should be in the classifieds in a couple of days.

Hardly. The V series has pretty outstanding thermal engineering (pretty much perfect if you add in a slot blower to exhaust the air that may accumulate above the gfx card), and the lower end models such as the PC-60 get very close to ambient through the simple mod of cutting out the back fan grill. Antec is certainly nice, but Lian Li is definitely a step up.
