Default Case swap...

I really didn't have much of a heating problem but was tired of sitting in front of my computer freezing my hands off trying to keep it running cool. I took the half of the double wide project that hadn't been chopped up yet and transfered my p4 set up in to it. This case has 2 80mm in back and 2 80mm in front. Wrapped all the wiring in uv clear flat wrap and what could be stealthed was. All fans are running full bore and seem to be moving a chunk of air. But dang it the temps are running the same as in the other case. Seemed like a lot of trouble for naught. I have already cleaned the system just last week and regreased the heatsink for the cpu and reinstalled it. I used artic silver 5.
I have some of that poster board that is foam in the middle and paper on both sides. I was thinking of making a shelf like partition that would seperate the bottom half from the top have just above the vid card. This poster board is cheap and easy to cut out. So getting full coverage is not a problem. I would then add a fan standing up in the front of the 5 1/4 bays to pull air in to the top half. Since the two fans in the back are stack verticly I could have one in the bottom section and one in the top.
Now that you are as confused as I am any suggestions?

Default Re: Case swap...

how big is the case? and are the front fans intake or exhaust and vise versa. There should be more intake than exhaust.

And i have no idea what you are talking about with the card board thing. Pictures would help.

Yes I would like to know what the specs were, too.
and what temps were running at what temp...would be nice too!
The splitting your case with the foam board might be a good way to truely isolate what the temps are.
Is it a stock heatsink on your cpu or is it an upgrade?
One other thing...Are you overclocking?

One thing that really is worrisome is the size of the cpu heatsink and whether or not you can reverse the attached fan to suck air through the fins and out instead of blowing air across.This sometimes actually leads to a cooler flow of air through your system.
I have reversed the fans on a few so that the air was sucked over the fins and really brought the temps down(even with just hot computer air). In as much as as your two rear case fans go...you might try to reverse the flow of one fan to blow more cooler air in from the rear so as to either blow over the graphics card or over the cpu fan and reverse that fan to cause a direct flow in and over. Or cut a hole in the center of your side panel and install a fan there to blow down on both the graphics card and cpu.
Need to know what may be heating too much to make you want to change cases to lower the temps to make a better proposal

Nice set-up!
First let me edit my previous posting ...fans need to be reversed <<so as to blow air away from the heatsink instead of down towards it>>.(really tired last night) This sometimes actually allows a cooler flow of air through a system.
But I am thinking that maybe...just maybe you are getting a false reading on high temps.
You should have more than adequate cooling for what you have installed (maybe under powered???)
But the question remains as to what are your temp readings and what are you using to determine them??

Hi Seti. It appears the cpu fan is running slow. Most run at 3500 rpm and faster as the temp goes up.

I have 3 to 4 pin adaptor. That has the pwm lead on it to connect to the motherboard. Let me try that and get back on. In the mean time here's the link to the pics. You have to go through them backwards. Go to the first cartoon drawing and go backwards to the top.

Default Well...

Knowing the Intel cpu chip is sturdy I unplugged the cpu fan and plugged in 2 different makes of 80mm fans. The first one a no name fan ran from the gate at 2500rpms and only fluttered slightly. The second was an Antec 80mm and started out at a little over 2800rpms only to fall off to 2500+ rpms. I saw as the temp went up the rpms went down. Looks like the pwm commands are inverted. Not good. Ok any fellow MSI Intel users able to comment on that.
I took some more pics of the system as it stands now. Same link as before.

seti,
alllll righty then, from the pictures and the temps, We now have something to work with.
Most definately the cpu fan is out of sync, and from what you said about the rpm dropping when temp rises(called reverse PWMx logic) and can be easily fixed with a utillity called speed fan(google for it) This allows you to control all the speeds and temps of your computer. It is a freebie and a great monitoring tool.
The cpu fan may also be a medium rpm fan that max's out @ 3000rpm and if that is the case needs to be replaced with a fan that has at the least a 5000 rpm rating so as to run between 4000 and 4600 rpm's which is about right for any cpu fan. But you can check out speed fan and then see if the values can be changed to support your board.
read the help file and you will see a notice about what to do for Reverse PWMx Logic. "F1" key opens help files.
The other thing that I would do is seperate those HDDs to allow more air flow through the center. As it is now the air is mostly directed towards the sides of your computer and really doesn't help you that much.
HTH

Default Ok...

Speed fan doesn't help. Tried it before. I'll get on the hard drive suggestion asap.

Default On top of all that...

I some how picked up a virus. A trojan really. Called Backdoor-AQH
Turns off active x controls and makes it so your anti virus dies. Got it squared away so now to unwrapping the wires and moving the hard drives around.

Sorrry, Took so long to get back.....went canoeing and relaxed a little.
Bad news the trojan...damn script kiddies...they all need to hung up by their privates & whipped by everyone that was ever infected by their garbage.
how the hdd move coming? nice job on the wire wrap, sorry to get you to have to dismantle and reasemble but it happens to the best of us. I have 3 drives also ..stuck in a raidmax case. The bottom drive I reversed so it would lay upside down on the bottom and then put a space between each of the others and they stay about 70 (F) with 2 fans running at 2400 rpms and then my cpu fan runs constant 4500 rpms @ 90 (F) Then I have an extra side panel fan (?rpm). Inside temp shows a constant
83 (F). But then again I am only running a slightly OC'd athalon 1800xp (1.83 ghz.) on a shuttle ak39n mobo with 512 ddr 400 with an ati 9000 all-in-wonder that I built about 4 years ago. While it is slightly lower in bench tests than some compatable machines it is the stablest machine I have ever been on. Only 1 time did it ever fail me in all that time and that was when a fan went out on the chip.
Keep me posted about the temps and I am trying to dig up some more info on that reverse speed problem.
later

I went ahead and got speed fan and couldn't get the cpu fan to go past 2519rpms. Put it on my fan speed controller and got the same results.
So I guess the cpu fan for some odd ball reason only goes to 2519rpms as top speed. The way the fan is mounted to the heatsink if I replace it I'll have to figure out how to make the heatsink stay on the cpu chip.
But you know the more I think about it the more it sounds like the fan has a built in thermal sensor and it's ignoring the pwm commands in favor of its own temp readings. I have search on aol and google and yahoo and dogpile with the numbers off the fan. Also been to the Intel site for info on the fan, no joy there. Guess I'm going to have to look in to getting another fan from Intel or an aftermarket fan.
As for the drives, I've been pretty busy lately at the hotel so have to wait till my day off thursday to do the shifting around.

Wow that fan doesn't just screw down into the heatsink on the corners as most others do? Strange hook-up there. I guess some more proprietary garbage to make you buy a lot more than what you need to get. Hard to tell from the pics but it looks like just a 60mm size fan. They make a plastic converter that goes from a 60mm to 80 mm for fitting on a heatsink or a case front/back. They also make a air tube for bringing air form a rear fan to deflect on to a heatsink. They are pretty cool as you can get them in different shapes and sizes.

Default Um...

The fan clips in to groves in the heatsink then the heatsink and fan as one assembly goes on the cpu chip. The sides of the fan have lock down clips that mate up with a peice that is mounted on the motherboard. It hooks to the posts sticking up from the motherboard. Then the latches take up any slack for a tight fit. Take the fan out and the heat sink comes out with it. I did find out it's a quiet fan rated at 2800rpms tops. Time to either figure out how to clip out the fan and keep the retainer clips or shop for a whole new HSF set up.

Default Yup...

The second one attaches the same as the stock HSF. At 6000rpms it's gonna get noisey but what the hey. Trouble I just don't buy over the net. I have seen that one locally somewhere.
But what I think I'll do in the mean time is get back on track the double wide project. Move the drives and the psu to the other case.
