Q9550 Running Extremely hot

[TheAmazingJordo]

I had been running my Intel Core 2 Quad 9550 (2.83GHz) not overclocked, and I decided to check my Core Temps, using Core Temp, and I realized a few of the cores are IDLING at 60 degrees Celsius.

I decided to replace the stock Intel Heatsink, with new Artic Silver paste and a Sunbeam 120MM Core Contact Freezer.

After getting the PC up and running, and reinstalling Vista, I opened up Core Temp, and lone behold thee EXACT temps as the stock Heatsink was showing. I spent over an hour installing this new heatsink, making sure the paste was spread properly, and everything was installed and set correctly.

I have no idea what the problem is, I'm afraid of damage because at 95-100% Load it starts going over 71 degrees and higher.

Are you sure you have a solid contact between the heat sink and CPU? Some people have to machine their heat sinks for minor flaws to get the best results. It's weird however that you have the exact same temp readings as with the stock cooler. That leads me to believe you have a seating problem.

Try looking at what real temps and hwmonitors give you, just to make sure it isn't Core Temps having the problem.

If those temperatures are accurate, then you do have a problem. Remember that with thermal paste, more is less.

I have my q9550 way overclocked with a Mugen 2, and it doesn't go past 62 (3.91ghz at 1.312v). At stock, the Mugen 2 literally *laughs* at it.

Also, what case are you using? Can you also check voltages on hwmonitor or everest or similar? What motherboard?

I've tried every temp program and it's all reporting the same thing.

I'm running my Q9550 with a 120MM Sunbeam Core Contact Freezer, all on a ASUS X48 Rampage Formula Mobo, inside an Antec 900, with a ton of fans. I just don't see how these temps are possible.

SpeedFan or Everest? Have you tried those? I have the same problem with a P4 box, temps don't change. It may be the thermal sensors.

 

[TheAmazingJordo]

I've tried all Temp programs and they are all the same. Thing that worries me is that it may just be a bad thermal sensor, but I wish they read like 40000 degrees so atleast I'd know they were bad. I think I'm going to give it another tear down on Thursday, and redo everything, again.

Check for humps or dents or make sure both your cpu and heat sink are flat, using a straight edge. Your cpu could actually have a slight bulge, and forces no contact with your heat sink. You may look into a lil lapping if so

 

[TheAmazingJordo]

What do I do if it has a bulge?

 

[AKM880]

You'd need to lap the CPU.

 

[JAYDEEJOHN]

Bulge or crown, with it rising towards the center, as an iverted bulge, or dip wont cause as great a problem, tho it all depends. Flat is good

 

[boulard83]

Check CPU and HeatSink for flatness. Lap if needed.

Buy better thermal paste ?

be SURE its nicely installed and tight. make sure the heatsink its sit on the CPU and that hes not touching any CAPS.

 

[royalcrown]

sure....lap = VOID warranty ! If you're worried RMA if you can !

 

[JAYDEEJOHN]

^^ good point, and mentioned this as thinking for the OP, and not advising him

 

[10tacle]

You guys talking about lapping the CPU or the heat sink? Everyone I know with this problem ID'd as a misfit has modified their heat sink to match up to the CPU. I wouldn't ever touch the CPU. That's just common sense - modify the cheaper part!

[boulard83]

Ive seen few concave stock CPU. This mean that if you only lap the HSF youll never see any improvement. The CPU only touch the Heatsink with its 4 corner. This mean that only the paste make the contact .... = bad

If the CPU isnt FLAT ... he can stil RMA it.

 

[TheAmazingJordo]

I bought my PC maybe 10 months ago, It's only like a 30 day thing though right?

 

[JAYDEEJOHN]

Nope, I dont think so. Should have a longer period than that. Think its a year for like HP and such

 

[boulard83]

you can use something like a blade ( FLAT ! ) to ensure Heatsink/CPU flatness.

 

[hok]

your suppose to lap both heatsink and cpu no?

 

[JAYDEEJOHN]

Yes, but you can just do one if the others already flat, or just do one , using it as a mold for a better fit, if you have to, saying you dont want to touch you concaved cpu, but you want you hsf to match it, by sanding/hollowing it out
