hey Tsf!

i just received a motherboard i ordered from newegg.com for a x58 build and the first thing i noticed when removing the board from the package was that one of the mosfet sinks were poorly attached. its not ridiculously loose but if u push the side of it slightly with you're finger it will detach from the thermal tape and rock to the side until i let go. (has a spring type fastener) I took a flashlight to the side of it and it seems like the thermal tape is making contact to the mosfets but before installing it i would like to get some peoples suggestions. Is it possible to take the heatsink off and replace the thermal tape? do they sell thermal tape at stores like microcenter, bestbuy or radioshack? i would hate to return the package and wait for them to send me another unless i really have too!

motherboard - Asus Sabertooth X58 Tuf series

I have a Picture below with a Red box around which heat sink that is giving me this problem.

been down this road many times myself; simply remove the heatsink / remove the existing thermal tape and apply a TINY dab of artic silver 5 thermal paste (or similar) and reattach heatsink .....then your good to go

 

[linderman]

once you get this system up and running with the OS and drivers / simply run sensorsview pro to check the temp of the mosfet / it will be reported as SYS temp

Hey, thanks for the speedy response =]

Tomorrow i will be heading to micro center for the last component of my new build - (cpu) I should have the system up and running that evening if not Friday the latest. I will download Sensorview pro as recommended and report back the temps to see if it looks alright with you. Thanks again for the quick response. =]

we are here for YOU

keep us posted with your progess!

BTW: thats an awesome board; my personal fav when selling socket 1366 systems! ENJOY

Okay i think we have a problems here =[
i just got done putting the pc together i bought some MX-4 and applied it to the every mosfets and re applied the sink on top of it and booted her up into bios, under hardware monitor it showed my cpu temp at 29c mch at 56c i left all setting in bios how they were "auto" i booted up windows and ran sensorview pro and instantly it popped up a warning sign showing "Sys voltage 1.21v it was in red letters and sys temp 57c was in red" i rebooted the pc and tried again and it showed it at the same temp 56-57c but this time the sys voltage was .95v is there some kinda of voltage i have to manually set in bios or something? when applying the thermal compound i put a small tab on each mosfet and securely replaced the heatsink making sure both pins were fastened. all the other sinks are sturdy as a rock, could it be that the others arent making good contact??

Ok after reading around apparently sys temp is often referred to vreg sensor and alot of ppl with x58 boards have been reporting temps of around 80-90c I also seen ppl saying that its the north bridge sensor?? Can anyone confirm it? It shows up as mch in bios which is weird because I thought i7s didn't have those and in sensor view it shows up as sys temp, both report same temp sensor view also shows sys voltage of 1.21.

**Update**

well after work i came home and did read quite a few forums came to the conclusion that these temps for the north bride are normal????! and i decided to check for stability. with stock settings 3.06ghz + HT Ram @ 1600mhz "Xmp" i did 30 minutes of small FFT's with prime95 and the highest temp showing at 62c, the sys temp hovered around 55-58c. so i decided to bump it up a tad and went to 3.8ghz 200/19 @ 1.24v Vcore + HT and i ran Small FFT's for 30 minutes and wound up with the highest being 71c Sys temp 64c, about to do the blend test for a few hours to check stability with memory. So far how do the temps,settings, voltages look? im still pretty new to these chips but i am SURPRISED so far with these temps / voltages compared to my old QX9650.
btw.. should i try dropping the voltages some or does it look alright for 24/7 use @ 3.8ghz with minimal cpu degrading? I will post a pic below.

your temps look good; the i7 runs hotter than the Q9XXX cpus do. if you pass stress test without hitting cpui temps of 80C I think you are fine

just for the sake of discussion; you did remove the old thermal pad from that mosfet right? and you applied the thermal grease no heavier than a thin coat of paint; right?

the northbridge does run much hotter than any cpu does

 

[Mottoman216]

Yes, the thermal tape was removed before applying the paste. i have been playing with the setting and i seem to get a stable 3.8ghz / 1600mhz ram but when i do the blend test it failed after an hour or so and i get a Bsod. i have HT on aswell as C1E and Speed step....should i disable c1e/speed step?? temps @ 3.8ghs never got hotter than 71c on all the cores..

 

[Mottoman216]

Okay well i upped the voltage a little 1.25v on the core and tried again it passed 1 hour of small FFT's and has been running blend test for 4 hours stable now max temp is showing 75-76 on the cores...im probably going to need a better cooler. Anyway im glad that im running 3.8ghz w/ht and im going to keep it this way as its more than enough for me, Thanks alot guys!

 

[linderman]

I would not disable speedstep as you will be running at higher voltage 100% of the time instead of allowing your system to idle when its not under load.

your temps do look good and adding an after market CPU is a very smart move; for a very affordable cooler (coolermaster 212) you can ensure your cpu is not subjected to useless heat

 

[Mottoman216]

I just went out and bought a Antec spot cool fan and placed it right on top of the NB heatsink and the temps are down to 40-45c max, as for the CPU cooler would the Coolermaster 212 out perform a corsair h50? im not liking the performance on the h50 so far i thought it would be better. oh btw i managed to drop the voltage to the cores to 1.23 and it ran Linx / prime95 for 4 hours each and no errors, also dropped my max temp on the cores to about 68-69c?

 

[linderman]

nice improvment on the temps! kudos

the H50 is a real dog in my boot and the radiator is a sealed unit; no user compensation for natural evaporation

the coolermaster 212 would be a smarter move or the coolermaster V8 if you can budget that
