Anybody else have this problem? Installing a retail Intel processor, heatsink, and fan on a ASUS motherboard was a tight fit. It deflected the motherboard just enoughtthat it was scary. After serveral repeated attempts to post, I just kept getting the error message; "system failed cpu test" over and over and over. Would not post for nothing. I tried everything...moving memory around, removing unrelated hardware (sound card, modem, ect.) Finally, by luck, I unloosened the 2 retaining arms and relieved the pressure and the system ran just fine.
I called ASUS on this and they are well aware of it as there are others reporting the same thing.
Asus' solution was to buy a new fan/heatsink. My solution was to take off the plastic retaining cage, file down the two tan colored arms, and reinstall. Worked like a charm. Not near as much tension on the motherboard, no deflection, yet firm enough to hold tight.
No noticed increase in cpu temperature as per Asus probe.

It is disappointing that their solution is it to put the burden of resolution upon the buyer, especially when it is a known issue.

I owe you many thanks, after almost a week of grueling effort, a couple hours google'ing the problem has saved me quite a bit of money and extra time, your solution works FLAWLESSLY. I don't reccomend filing down the plastic though.

Meant to say, don't recommend filing down the plastic arms unless you're prepared for a bit of a mess, and as a note, the locking assembly comes apart from the fan/heatsink, and the control arms snap out of the locking assembly, make sure you play with the device so you know which part to file (meaning the part of the arm that contacts the fan/heatsink assembly when locked into position).

Wooohooo!! I've been trying to figure out this prob all day. I tried your fix and it works great! Big props.

What exactly are you guys filing down? Im confused if you guys are filign down the arms to the heat sink, or the brackets on the motherboard.

Do you have to remove that retaining clip off the motherboard? Any help would be appreciated. Thanks.

see my post on same problem here:
http://hardwareanalysis.com/content/topic/8069/

why would resetting cmos fix the problem if its just a tight fan ?

mind you I do think the fan was tight when I installed it and I'm considering a 3rd party one.

Sorry. My message disappeared. I'll try again.

The CPU fan being squeesed to tight is probably not the real problem but just accelerates it.

Read the real problem by MechaBouncer (on the middle of the page):
http://techsupportforum.com/showthread.php?s=&threadid=610...genumber=3

Picture of the problem from Jso-2:

This was the real cause of my problems. The problem is taht ju will loose your warranty just by checking if you have this problem. And definately if you try to fix it.

I had same issue. No POST with normal setup. Immediate POST with heatsink clamps undone.

Current fix: shaved 0.5 mm (approx) off of the top inner lip of the heatsink retainer bracket which is attached to the mobo. Works great.

When I took off the bracket from the mobo, I tried to look for the solder spots (I have done electronic and IC repair before) but didn't see them. Also, the way my retainer bracket is designed, it looks like it only touches the mobo at the through-hole standoff circles anyway.

Update (two days later) (weather colder.. factor?)
Won't POST. Undo the clamps. POSTs right away.

Will take off another 0.5 mm.

If this doesn't work, I'm going to order a thermalright slk900.

Please keep this thread alive. Perhaps it'll help the next guy...

Can someone comment on this, to put my mind at ease?

As in thread above, I had to cut down my heatsink retainer.

Current CPU temps are 30 C baseline and then peak of 48 C when running multiple CPU burn-in cycles using SiSoft Sandra. Is this bad or OK?

Hi Christopher,

You are so on the money !!!

I'm on my third motherboard... release some pressure on the CPU, and bang, the thing jumps to life !!!

What I really want to know is, where are the pictures of the solder blob ?
I really want to see exactly where the blob is, I can't seem to locate it.

Thanx dude,
Brettbear

Okey I got the same problem and changing heat sink solve it but... Is there any point in replacing this mainboard for new one. On every new the same thing will happen. Is is something really bad that those bulbs melted a bit maybe they will anlways in some time because that are straight under this CPU retainer?

Anyone know whether the soldering point problem (Mechabouncer) still exist for the latest Asus P4C800 Deluxe? I just put together a new system based on the P4C with P4 2.4C, Corsair TwinX pc3200 512 Mb, Nvidia GForce 5600XT, and using the Intel retail box CPU heatsink. The system does not POST, no video, no BIOS, ever. It beeps 5 times that indicates CPU error, but I tested the CPU working fine on a Intel 875PBZ system. I looked at the target problem soldering point as picture in http://koti.mbnet.fi/~nightops/eki/DSC00249.JPG, but found it totally flat, with nearly no solder, without touching any other points. Does it mean that this mobo has other problems and I should simply do an RMA, or there is something I can try to make it work.

Please help. Many thanks.

Vicenzo

I have the same problem System failed CPU test, but my model #: P4P800-Deluxe. I wonder if this the same problem?

I had this annoying System Failed CPU Test..

Solution: http://bq.fi/20040505power.jpg

This SHOULD be connected to the mobo :p
