You guys were right when you suggested that the intake fan by the hard drives wasn't doing it's job. As previously suggested, I removed the side panel. Idle temperatures dropped from 44 to 37. That's an 7 degree difference right there! Guess this means I definately need to cut a hole and add an intake fan in this side panel.

Or buy a new case that will have a 120mm intake fan in the front panel already installed. My case has 2, front and back but it also has honey-comb panel wholes which some air filters.

That part on the side panel being remove, maybe but I've heard it works for some and it won't for others but in your case it sounded like it did so time to DREMEL and some fan guards then.....

Though, next time get a Pure Copper for a Zalman or get the Tuniq Tower 120, proven to be better or best air cooler for a P4;

ya you need to place a fan in the side panel,preferably a 120mm, then also that fan by the HDDs.... all that one is doing is just blowing the hot air inside the case around....if you put it on the front panel and have it sucking in cool air, then an exhaust fan sucking the hot air out, that alone will drop temps...

I would also get a new CPU cooler like the Big Typhoon, the Zalman CNPS7000 and 7700 series are utter garbage, my 7700cu kept my CPU OCed at 3.45GHz at 50-55c idle and 66c full load, if I 100% loaded both theoretical cores (Hyper Threading) the temps could soar up to 73c!! Now with my Big Typhoon, I OCed even more, to 3.75 with a bit more vCore and my temps are 26-27c idle and 34c full 100% load!! That is definitely worth $50 considering the big typhoon is QUIETER than my old Zalman on low and cools a LOT better than the Zalman on high lol.

Nice OC, you have some killer RAM. Running at 960mhz!

Anyways, I would recommend a Big Typhoon for kerunt. It's only around $50, but the installation is a pain because you have to remove the whole mobo, but it's worth it in the end.

you must be one lazy person if you call removing the mobo a pian.... its good to remove and rebuild the system all over again anyways...you can clean everything while its all apart,which inturn helps with lower temps... and the BT isnt a pain to put on, i just insatled one a week ago and it was easy and simple as cake!

It's my opinion, you don't have to criticize me.

Hi all,
After joining this forum yesterday, I found out what I suspected all along: my system is too damn hot.

Idle CPU temps are around 44 degrees.
After 10 mins of STRESS TEST in Prime95 the CPU was at 60 degrees, and stayed at that temperature until I ended the test 3 hours later.

I need to cool my system down - preferrably with AIR cooling. Not willing to invest in water cooling just yet.

I have a Zalman 7700 AlCu heatsink, and 2 120 MM fans. Look at the below pictures for details .

The fan by the hard drives is an intake fan, sucks the air from the harddrives and feeds it to the back case fan, which pushes it out.

Will adding more fans help? What kind of fans? Where should they be placed? (I tried to take pictures of all angles so you can advise me better as to the location.)

I have that case--I know what you need to do and it won't cost you much but time. With the side panel off carefully measur from the top and back of the case to the dead center of the Zalman (Ihave that exact cooler btw) replace the side panel and using those measurements mark the exact center that you derived earlier on that panel (use a bit of tan masking tape and a fine point marker). Make a hole for a 120 mm fan from that center mark. make the 4 mounting holes (use a fan or fan grill for a template) and here's where there are some different options.

1) Mount a Nexxus SIlent 120 using a silcone gasket or O rings and be done with it--that wil not only provide plenty of cool air for the Zalman, but also pressurize the case and make number 2 an option to consider....

2) Perform Mod 1 and also cut a blowhole in the top--this will take careful placement--be sure to remove all your elctronic bits before cutting into the case--an 80 mm would be sufficient, but a 92 or even a 120 might be better--depending on the length of your optical drives/cables.

3) Preserve your hearing and mount a 92mm (like an Antec) and use a cheap PVC 3" to 4" Dryer Hose neckdown (about a buck) and carefully cut it with a sharp utility knife to fit over the sides of the fan body snugly--the 4" side against the fan/side panel; the 3" side about an inch from the center of the Zalman when the panel is closed. I have done this and it dropped my temps immediately--it is essentially force feeding the Zalman and nothing else.

Change out the Rear fan from Antec--or use it in the side panel and put a more potent fan on the exhaust.

From my experiments the center fan behind the hard drives did nothing to lower CPU temps (but it did help keep the SCSI drive cool

I've attached pictures of what I'm suggesting--it worked well for me.

The clear acrylic piece the antec mounts to is a 120 to 92 adapter I got from Coolguys--the 120 was too loud for me. I tried a 92 to 80 adapter I also have laying around and it was too restrictive--the home-mod dryer hose thingy out of PVC was better.

The case was a Lian Li--but I know the Sonata well (I'm looking at it) and the mod would work for that case fine.

I went out and bought some Arctic Silver 5 today, along with another 120 mm fan (same one as I got on exhaust at the back of the case).

Took everything apart, got rid of the old thermal compound, cleaned everything nicely, applied AS5. Idle temps have dropped about 2 degrees. I was expecting more, but this is still better than nothing. Although, I have a feeling I may have put too little of the compound on the chip. I did like the official AS5 Instructions said - 1 "grain sized" blob of the compound in the middle of the CPU, then popped the heatsink on and proceeded to assemble the computer back together.

I actually got this heatsink only about a month ago, so I don't really want to change just yet... maybe I'll pick up one of those famous Big Typhoons towards the summer . Removing the mobo isn't too bad, I had to do it today when applying AS5 .

CyberDruid, thanks for the info and pics .
I'll definately add a side fan this weekend.
