CPU Temp High

[LegendofJubei]

Hello,

Hoping somebody out there can let me know what's going on with this...

My idle CPU temp is 40+ degrees which seems quite high to me given the system specs:

Case: Antec 900 (4x 120 MM fans (optional side fan mounted), 1x 200 MM fan
Mobo: ASUS P5Q Deluxe
CPU: Intel Q9450
RAM: Mushkin XP PC2-8500 DDR2 1066
Video Card: HD 4870 X2
Heatsink: OCZ Vendetta 2 (using MX-2 thermal paste and a Noctua PF-12 fan mounted to heatsink)

My Mainbord temperature shows 24 degrees, CPU temp is 43 degrees, Auxilary temperature 34.50 degrees (according to SiSoftware Sandra).

The other thing that's aggravating is that all fans are set to high speed. I took everything out and remounted the heatsink and I'm getting the same result. I read alot of benchmarks/reviews on this heatsink etc. and I'm not getting anywhere close to the 20 degree idle mark that they're representing.

I'm inclined to believe it has something to do with the cheesy pushpin design but other than that I have no idea what else could be going on. Is anybody else experiencing this or does anybody have any helpful ideas ? :help: Thanks

I have the same HSF, the best advice I can give you is replace the push pins on the mount with the Thermalright LGA775 Bolt Through kit, keeps everything nice and secure, far better than the push pins. It will also give you a chance to double check that the thermal paste is ok on the bottom of the Vendetta, it seems like the direct heatpipes are pretty pick about how it's applied.

I have the exact same case, CPU and Heatsink (with noctura PF-12)... and I hate the pushpins more then anything... I can't even get one of the pins in... soooo my temps are around the same as yours... now when you say your CPU temp, what are your core temps? My temps are 39,36,35,32 on idle.

Also what is the temperature in the room? Makes a big difference!

I just bought the Thermalright LGA775 Bolt Through kit, and will get it soon... so I can let you knwo how that works out, or you can just buy it yourself.

ps. I dout your actually going to get 20 deg idle... unless your room is very cold...

i have the Vendetta 2 and the Thermalright bolt through kit does not fit on the heatsink. it doesnt fit around the base.

It works just fine on mine. All I did was put the backplate on, snap the stupid push pins off the OCZ retention bracket, and bolt it down. Snug as a bug in a rug.

Are you sure?

Take a look at this page:

OCZ Vendetta 2 CPU Cooler Review

The position of the pushpin holes don't interfere with the heatsink!

You would have to install the heatsink with the fan mounts before installing the fan.

so you popped off the pushpins and bolt'd it through there?

the kit i bought came with a metal retention thing.

there is a picture, that metal thing won't fit through the heatpipes of the Vendetta 2. So i bent the metal to make it fit but then the Vendetta is too wide for it to sit flush. Sorry for thread jacking, but it has to do with compatibility?

Hmmm..hoping I can get confirmation on this. I already purchased the bolt-thru kit because I can't stand the pushpin. I have a feeling the pushpin isn't secure and because of the weight of the heatsink, it's bending ever so slightly at the top (lifting it off the CPU just slightly) due to gravity. I could be wrong but I'm not liking this 40 degrees idle bit. I was hoping to do some overclocking on this cpu but I'm not comfortable even trying if it's sitting at 40 idle already with 6 fans blowing at high speed and a supposedly high-end heatsink.

Only reason I'm choked is because my junky computer with an old AMD 95nm chip in it is running at 22 degrees idle with just the stock amd heatsink on it and 1x 120mm fan in the front of the case. Doesn't make any sense to me at all...but I'll let you all know what happens with this bolt-thru kit and I think Jon_di2 has a similar build and is doing the same with the bolt-thru.

Let me know how the install goes Jon_di2...it'll make my job that much easier

Yes I popped off the pushpins and bolted it through.

It only took me 2 minutes to get the backplate and spring loaded bolts installed on my heatsink.

This is the one I bought:
NCIX.com - Buy Thermalright LGA775 BOLT-THRU Kit for for Ultra 90/120 & HR-01 Retail Box - BTK-LGA775R In Canada.

Your backplate is not the same as mine.
