What are safe temps for the P4 LGA 775

[Wizzard005]

Hey all,

I have a ASUS P5WD2 Premium motherboard and XMS 5400 DDR2 with a P4 3.2Ghz LGA 775

This CPU seems to run hot, like 72c when running games. I have the best some of the best stuff you can buy , see pictuers:

When the PCU runs at 3.2Ghz , its about the same temp, so i am wondering if the monther is reporting it wrong maybe?

I am tring to get 4.2Ghz out of this, its Prime95 stable at 3.85Ghz , but i need to figure out what the deal is with these temps.

What is a good CPU heat monitor I should use? The AI booster I think is crap...

[exhausted mule]

i have the same mobo with the same cpu.

mine is overclocked to 4 gigs for just whatever right now and load/idle is 40/48 with average ambients.

at 4.4 its just a few degrees hotter and i'm wondering if your cooler isn't seated properly.



if its a stock/non lapped cpu i would suggest doing it. but either way, you should be getting above 60 degrees at most. Download "throttlewatch" and see if its throttling. probably is, if so, try lapping and reseating and see if that helps.

[Know Nuttin]

Does the heatsink "feel" like the CPU might be 72c when under load? Are the heatpipes warm?

[KJSatz]

Could have gotten unseated somehow, or you might have a busted heatpipe. Are temps that high without any overclocking/overvolting? If you have the time and thermal paste, I'd recommend taking off the XP-120, putting on the stock HSF and seeing if temps aren't insane. Then take that off and reseat the XP-120 and see if it's working alright. If the stock cools okay and the XP-120 gets higher temps, email TR.

[Wizzard005]

I just dont know, it feels to me like the motherboard is reading the temps wrong. How can it be around 72c at factory clocks? It cant right? Its seated fine and I have re-checked it. I think the problem is in the motherboard or maybe the CPU i have is mesed up? I mean on idol it changes from 3.2Ghz to 2.8Ghz keeps flipping back a forth, maybe i have a setting wrong?

Are you using the LGA775 RM by any chance? If so this will explain the heat problems. If you take notice, this unit is made of plastic instead of metal like it's 486 brother. When you attach your xp120 it simply doesn't apply the needed pressure on the CPU because the plastic wil flex under extreme pressure, IMO.
And the fact that I too had suffer similar problems that I didn't experince when I had my xp90C installed on my 486 system.

How can I tell without takeing the CPU out? Also, the heat problem means its something that will not go away unless I get a new CPU right?

Will comething in CPUz tell me what rev it is?

[Sentential]

Your heatsink is backwards which is half of your problem. When you mount that heatsink on the P5WD2 you have to put the heatpipes to the left so that it seats fully on the heatsink.

In addition you probably did not use enough paste since intel IHSs are incredibly bowled out which hampers good contact on a spring based heatsink.

Also it looks like you have a great deal of dust on your heatsink, clean some of that out and see if that helps. As for temps on the P5WD2 anything under 60C overclocked on load is considered normal. My 920 @ 4.2ghz @ 1.375v loaded around 57C with dual burn-in.

I have to change it? You have a pictuer on how it should look? I think its seated right, however I may be wrong as you said.....

This is how yours is mounted:
http://home.tiscali.nl/rmbrouw/a8n%20sli%20pc/xp%20120%20placing.jpg

Because of the way the LGA bracket sits the heatsink on the core it needs to be like this:

http://journal.mycom.co.jp/column/jisakuparts/007/images/004.jpg

You see the problem is that the heatpipes do not fully extend through the base of the heatsink. When the pipes are facing the rear of the case the base of the sink is flush againt where the processor would be under the IHS and it gets full contact with the heatpipes which helps the transfer of heat to the outer fins.

I tried mounting the XP120 like you have with the heatpipes facing towards the ram socket but my temps were exponentially higher than what it should have been. When I reversed the heatsink into the position I described the temps were back into an acceptable range

Its cant site the other way. There is a heatsink in the way on the top

what are your thoughts?

[Sentential]

Lawl.. Dude I have your exact board look at my signature, it does fit I can assure you of that because its fine on my backup board.

The heatpipes fall far short of clipping the FET heatsink you are refering to.

D94 will also agree with me, he had the same problem as you and his fits perfectally in the position I described, also on the P5WD2

[Wizzard005]

can you show me a pictuer of it like that in the P5wd2 Premium? , so i just need to flip it around?

Is this way its not sitting fully on the CPU?


not tring to sound dumb, its just a pain in the butt taking it all apart hehe

[Evilsizer]

watch the monent he gets it right his load temps will be around 46-50c load.

*edit*
reread one of his post.. he already showed you how to mount it correctly

once i can confirm the mount, I will take this crap apart and flip it around, what a pain in the butt :) I guess this is why even with the fans on full speed, it still gets hot..

[Wizzard005]

by looking at the board, the heatsink by the printer port will hit the XP-120, i think that is why i did it the way its mounted now, however i may be wrong... the one in the pictuer is a MSI board...

Its late and Id have to figure out where my camera is. But this is coming from somone with your box with you exact same problem. Our setups are for all intensive purposed identical.

You are just going to have take my word for it until tommorow. Since clearly you dont belive that I have your motherboard I ask you to look at this:

http://img.photobucket.com/albums/v180/Sentential/DSC00161.jpg

(Yes that is my primary box)

Dude its not going to hit anything. You secure the front two clips by the RAM slot first, pull ward and use a screwdriver to pop the rear ones down (by the sink you think the heatpipes will hit but im telling you they will not)

Again you can choose to believe me or not, I have your setup with that same heatsink and Im telling you the solution to your problem.

[Wizzard005]

Sentential,, I am not tring to be a jerk, just the boards your posting are not the P5wd2 Premium, so I am wondering if you do have the same board or something simular to it? The ones above the mounts are totally different,...

[Evilsizer]

dude mounts are not different. all lga boards have the same 4 hole around the cpu. the difference is some heatssinks use clips like yours, others use the 4 mounting holes. his board is the same as the one you are using. JUST flip the heatsink and be done with it.
IT WILL FIX YOUR TEMPS.
the longer you take at fixing you hs mount the more prone you cpu is to being damaged, when its running that high temps.

[Wizzard005]

All right, Off to take my PC apart again!, still have some thermaltake heat paste see what happens, will take pictuers to put up here in case i run into a problem :P

wish me luck, temps are 70c now, see what they change too..

[Sentential]

Sentential,, I am not tring to be a jerk, just the boards your posting are not the P5wd2 Premium
The one I said is my primary box from post #17 is the one I am refering to. Anyway here is a screenshot from the PC I am posting from :)

[Sentential]

Oh also, forgot to mention this. When you mount the XP120 in the position you have the front part of the heatsink's base rests against the capaciters that are by the socket and force the base at an angle since the capaciters are higher up than the floor plane of the CPU's IHS.

Most likely your temps are caused by the heatsink's poor contact (or lack there of) because it was mounted in the improper direction as I have been trying to explain in previous posts.

How can I say this, you were right all along! I did what you said, I took it out, flipped it around and then put it back together.

However, My screw drivers slipped and gashed the MB LOL.... anyways, needless to say, I am out 200 bucks now for my dumb mistake LOL...

It cracked the MB, it was a mistake LOL< but since I live in Hawaii, its not like I can run to the store tomorrow and pick up a new one LOL...

Anyways, when i wake up in the morning I am going to order a new MB from Newegg / or tigerdirect...

Now, this was the 955x chipset, should I get the same board? I still have the 775 540, and there is nothing wrong with it..

What do you think?

Get the same motherboard, or is there something else better then the P5WD2 Premium

[Sentential]

How did you manage to crack your motherboard with a screwdriver? :eek: Most of the damage I have seen from similar accidents result in scratched traces not a completely cleaved in half mobo.

Most of the time i dont even need a screwdriver to pop the rear latches on I just use my hands.

Have you tried the motherboard since the accident to see if it works or is the damage to extensive?


If you scratch a trace most of the time the motherboard will still work perfectally fine.

[Wizzard005]

How, well I was rushing :P Anyways, I tried to turn it on, it turned on and then nothing, said something about USB and then I turned it off, and that was it.. It wont power up anymore hehe...

Anyways, I guess this gives me more of a reason to order a new mb and prossor, I wanted to ask you Sentential, Is the Pen D worth it? Should I get the 2.8 or 3.0? I was thinking of ordering the same MB, but I figured I would get a CPU too and wanted to know when one i should get.

Yours is the Presler, should I find the same? If i do, what clocks do you think i will get on the xp-120 I think the 2.8Ghz Pen D is 174 and the 3.0 is 199 atm... I dont think its the Presler tho, not sure if that matters...

[Captain Helghas]

If you get the Pent D 930, you can expect ~4.0GHz at least on the P5WD2 Premium. Before you go about buying a new mobo, you might want to contact Asus and see if they will repair it for you. They usually charge me a fair price.

If clocks are what you want then presler is the chip of choice. As for clocks its a bit of a mixed bag since its a split die chip. Most people are getting in the range of 3.8ghz to 4.4ghz on air with most just over 4ghz. My 920 did a little bit over 4.1ghz and water brought the total speed short of 4.3

If you are going to order a new motherboard you might as well get the intel i975XBK rev304 which will support Conroe and the rest of the NGMA next gen processors. Current i975X boards do not support conroe, the only one that does is rev304 of the i975XBK Bad Axe made by intel themselves

Anychance you have the part number for that P940 presler ? So the 2.8Ghz and the 3.0Ghz will be good choices?

It would be nice to get at least 4.0Ghz on Air useing the ASUS P5WD2 Motherboard...

[TWY]

I've mounted my HSF the same way as Wizzard005. However, mine is the Thermalright SI-120.. The base seems to be shallower, and does not clip the metal capacitors, but yet I'm getting almost the same temps as him..

My room temperature is 30°C.. I'm using a 940 chip, and when it's clocked to 3.84GHz (240FSB), I get 68°C load.

And at 4GHz (250FSB), I get 72°C load, but it fails Prime95 or gives me a BSOD with some PFN_LIST_CORRUPT error.. I upped the Vcore to 1.325V for 4GHz, but I'm unsure whether there is a need to go higher?

Or it is a sign I need more than the default 1.5V for the chipset?

[Captain Helghas]

You've got a heatsink problem there TWY. I recently put a 930 on a P5WD2-E with a SI-120, and immedaitly clocked it at 267FSB. Load temps were 57C at 28C ambient. Edit: I forget what exact fan it was. Some thermaltake fan that is either 21db or 27db. It was a buddies rig I helped him with, so the specs escape me somewhat. But I'm sure of the temps and the clock.

[Wizzard005]

I ordered the P5WD2-E Premium with a P4 930 CPU for 400.00 bucks! Should I be able to get 4.0Ghz at least useing the XP-120?

I have one of those COMPUSA thermal fans, 1000RPM - 2100RPM.

I guess it will arrive in a few days and we can see from there. I will take pictuers and stuff when i get it all setup.

You'll get 4.0 easily, as long as you don't break this one. :cool:

I think you might be the only one here which has that fan. Most use a Delta or Yate Loon, depending on their tolerance for fan noise. Also, FYI, fans' RPMs are useless. There are really only three stats that are important: Pressure (mmH2O), Flow (CFMs), and Noise (dB).

[Evilsizer]

yea but noise is not always rated the same from manf. to manf.
the yateloons move some air with very low noise, got them in my p4 box. its actually the most silent box i have built.

What's your idle temperature and which way did you mount your SI-120?

[Captain Helghas]

What's your idle temperature and which way did you mount your SI-120?
It was ~40C @ idle with a 25C ambient. The SI-120 was mounted with the large heatpipes nearest to the Asus NB heatsink. I can go to the guys house and take a picture for it if you would like.

I'm getting about 48°C on idle.. And I have no idea why.. :cry:

God I hate waiting for Fedex to come with my new Motherboard and CPU :( .. The tracking says it should be here tomorrow I guess. Damn , living in hawaii is the pits when you want something ASAP.

I will be putting this new setup in my silverstone case......

Never rush with electronics, they are delicate things, i hope u learned a lesson. Also follow the instructions that come with heastink and waterblocks.

[einstein2]

well dependant on cooling type, mine stays around 34 to 45c, while the MB is around mid 30s.

[TWY]

Sure, just give me a while to stop by my buddies house.

Thanks man.. Any pics yet? :D

[Captain Helghas]

I'll get them today, I promise (I lie sometimes though. :D). If I remember my digicam it might even be a good picture, rather than from my phone.
