Prolimatech Genesis: My experience so far

post #1 of 41
Thread Starter 
So I just installed a this CPU cooler. I have to say, quite good mounting system, or so it appears. It allows you to remove the cooler with 2 screws once the mobo mount is installed.

So I am currently "burning in" the paste; 1/2 hour prime95, one hour off, rinse and repeat (on second cool down period). The mount seems solid; little tight but it looks like i have good contact. I spread a very thin (almost transparent layer) on the cpu and the heatsink. the heatsink has a slight machined groove so i filled it in with a very thin layer. I have seated a few heatsinks before, same method each time.

The 2 140mm Blue Vortex fans are plugged into the mobo. Bios says they are running at about 970 RPM, which is just slightly below their rating.

I am hoping for the best, but right now prime95 is running at 75-80c at stock speeds. The Hyper N520 was running that same temperature at a 30% OC (1.3065v). I have a feeling the paste is not going to help that much once its set. I will try to re-seat it and see what happens. The fans seem to be set as intended: Blowing down on the RAM, and towards the back of the case.

Can anyone suggest anything I could try to remedy these issues? I will post pics and screens when I am done setting the paste.

Any suggestions are appreciated.

Other than that, it a fine piece of equipment, and pleasing to look at.

thanks in advance!

Check the base and see how flat it is. Maybe it's not completely flat. You could always lap it at that point.

Don't spread the paste. Let the cooler do that for you. It'll do a better job. Use a rice grain sized amount of paste on the centre of the CPU, then mount the cooler. Make sure the fan headers are set to max speed as well.

Enable speedstep if your overclock is stable.

Spreading TIM yourself is a bad idea as it can create air pockets. Like linkin93 said, it's better to put a small amount in the center of the cpu and let the pressure from the heatsink spread it. If you put it on both the cpu and heatsink you likely put too much on, which is bad for temps.

What's the ambient temperature? The delta might be normal but it depends where you start.

Thanks for your replies!!

Sorry, was at work and then reseated the heat sink.

My ambient temps are ~24-25c.

The base seems very flat when compared to a ruler.

I took everyone's advice, and applied new paste in "skinny X" form and let the heat sink do the rest.

I plugged the fans into the PSU VIA molex.

It is very nice... 2 screws to dismount and apply new paste!

One very important thing to note: I believe it is only an issue with the LGA775 platform: The bolts that hold the secondary brackets to the mobo, are sticking out too much and interfering with the heatpipes. Tightening them leaves a small "dent" in the pipe. See below:



Running Prime95 on and off now to set the TIM. Will be back with temps/screens and rep for everyone!

Thanks again so much!

Ok... A few pics:

All in all...

For me... It was a waste of money evidently. Unfortunately I do not see any improvement over the Hyper N520. Supposedly, the Pk-1 TIM needs no curing time, so I don't think my temps will get better. The only things I can think of is that the case just does not have the airflow to to accommodate better temps, at least in the case of this particular cooler, or this chip just runs too hot at this voltage.

Re seating the HS provided a vast improvement over the original temps, but still sub optimal...

Temps below:



Thanks for your replies. Going to put my goals on hold with this system.

Temps don't seem right somehow. That Genesis is supposed to be a few degrees better than my Mega from what I've seen. And PK-1 is awesome TIM...I used an entire tube and it'ed worked great for me.

Re-apply the TIM and this time, do like linkin93 suggested: place a "grain of rice" sized dab of TIM right in the center of the cpu then carefully lower the Gen onto it and fasten it down. Also, make sure you are tightening it all the way down--those bolts should be milled to stop on their own once they get down all the way. <-- This is how I mount my Mega and it's given me the best temps out of all the application methods I've tried.

See attached: What's in the blue square is all you are worried about.

Good luck.

You might still do something wrong. With the genesis i got similar results to a silver arrow or d14, most reviews do actually:

(same temps as the d14, 1 degree behind the SA)


Are you sure you did everything right and there is full contact, etc?

Best course of action is to contact Prolimatech, i assure you they will reply if you're polite. You can send them a message from their official website. Be sure to mention the problems with the heatpipes hiting the screws, which in terms might prevent the holding braket to ensure the proper pressure.

Secondly, if Prolimatech doesn't give you a solution (imo it's a serious design problem) contact your retailer and talk to him about your issue.

LE: Case cooling might be limiting you a bit also, i see in the pics it needs a good dust off too.
Also your CPU is from the old days and i don't quite remember what voltage is considered normal for that overclock, although i had the impression (which might be wrong) that the Q9550 would handle 4 Ghz on good air coolers.

LE2: As a precaution you should revise/redo the installation of the backplate to ensure you didn't forget anything.
