jay05 Posted November 22, 2010 Share Posted November 22, 2010 I recently purchased the H70 and getting relatively high temps. The stock heatsink gave me a minimum temperatures of 40/35/38/35 degrees With the H70 as an intake I am getting minimum temperatures of 36/29/34/30 degrees. As an outtake, I'm getting minimum temperatures of 36/31/35/32. This is at stock settings with my i7-950 at 3.06 ghz. My room temperature is 20C/68F. Is it really worth $110 to lower the temps by 4 degrees? I have tried to reseat the H70 pump with AS5 and still getting similar results. I applied by applying the thermal compound vertically on the cpu and spread an even amount with a credit card. I overclocked to 3.8ghz with the following settings. Ai Overclock Tuner - Manual CPU Ratio Setting - 21 Intel ® SpeedStep Tech - Enabled Intel ® Turbo Mode Tech - Enabled BCLK Frequency - 181 PCIE Fequency - 100 DRAM Frequency - DDR3 - 1451MHz DRAM CAS# Latency - 6 DRAM Clock DRAM RAS# to CAS# Delay - 8 DRAM Clock DRAM RAS# PRE Time - 6 DRAM Clock DRAM RAS# ACT Time - 20 DRAM Clock CPU Voltage 1.20000v CPU PLL Voltage - Auto QPI/DRAM Voltage - Auto IOH Voltage - Auto IOH PCIE Voltage - Auto ICH Voltage - Auto ICH Voltage - Auto DRAM Bus Voltage - 1.64v DRAM DATA REF Voltage on CHA - Auto DRAM CTRL REF Voltage on CHA - Auto DRAM DATA REF Voltage on CHB - Auto DRAM CTRL REF Voltage on CHB - Auto DRAM DATA REF Voltage on CHC - Auto DRAM CTRL REF Voltage on CHC - Auto Load-Line Calibration - Enabled CPU Differential Amplitude - Auto CPU Clock Skew - Auto CPU Spread Spectrum - Auto IOH Clock Skew - Auto PCIE Spread Spectrum - Auto C1E Support.................. = [Disabled] Hardware Prefetcher.......... = [Enabled] Adjacent Cache Line Prefetch. = [Enabled] Intel® Virtualization Tech. = [Disabled] CPU TM Function.............. = [Disabled] Execute Disable Bit.......... = [Enabled] Intel® HT Technology....... = [Enabled] Active Processor Cores....... = [All] A20M......................... = [Disabled] Intel® SpeedStep Tech.. = [Disabled] Intel® C-STATE Tech........ = [Disabled] http://i53.tinypic.com/2my9sso.jpg I'm trying to get it to 4 ghz but the temps are too high. I will need at least 1.3X volts and 191 BCLK which will generate more heat. Am I doing something wrong here to have such high temps? Link to comment Share on other sites More sharing options...
djmorgan Posted November 22, 2010 Share Posted November 22, 2010 What are your OC temps? I assume the above temps are at stock? They are normal, run your OC on load and report back what the max temp is! The H70 shines at higher temps. Search this forum for other examples and results.

djmorgan Posted November 23, 2010 Share Posted November 23, 2010 you don't need to list your OC details here, this forum is only for cooling. At a max of 61c you have a winner! remember a cpu can run up to 100+c but will be very stable and desired temp are at under 85c. Nobody gives brownie points for "mine is cooler than yours" because there are just too many variables to consider, ambient temp, humidity, case airflow etc. So be happy with your OC, your not in any danger from the CPU and go and do something productive with your computer like calculating the next convergence of the big bang :-) Link to comment Share on other sites More sharing options...
jay05 Posted November 23, 2010 Author Share Posted November 23, 2010 Here is an update. You were right. The H70 shines at higher overclocks. I just had to reseat it and screw the pump in as tight as possible to the cpu. Got it OCed to 4ghz with 23x and BCLK 174 http://i56.tinypic.com/2w2or3k.jpg Link to comment Share on other sites More sharing options...
Hapatingjaky Posted November 25, 2010 Share Posted November 25, 2010 From your pics you are running at 2GHz? with a Multiplier of 12x? You may want to recheck that Overclock because according to the specs of you OC you have stepping disabled so it shouldn't downclock at all. From the pics you are not running at 4GHz. Anyways I too have been having issues with my OC, I used to have an old I7 920 with a Corsair H50, used it for about a year then upgraded to Asus Rampage III Extreme, Patriot Viper 2 Sector 7 8,8,8,24,2T, Core i7 950 and the Corsair H70. Before I was running at 201x21 at 1.4V at a load of 70c, 71c, 60c, 70c. Now though I am running at 23x 174 at 1.35v but my temps are low to mid 80's on load. I've tried to reseat but I've had no luch lower temps. Pump is working fine and it seems to be seated fine but I was hoping for a lower temp using lower voltage. Kinda has me a bit worried. Going to be taking the system apart tonight and start from scratch again. Link to comment Share on other sites More sharing options...
XAFAfterShock Posted November 28, 2010 Share Posted November 28, 2010 are you using the adhesive pads on the backplate, I noticed when I had them on it really hampers the mounting force because it just makes the corners flex on the plate, I could pull on the waterblock and see the backplate flex so I removed the pads and remounted and it seems like there is alot more mounting pressure. if the pads were half as thick they would still hold the plate to the mobo but wouldn't cause the backplate to flex as bad as they do now.

Yeah the pads are on. This weekend I pulled the entire system apart, cleaned the rad aswell as all the fans. Used Arctic Clean to clean the CPU and the H70. Spread out a nice even layer of AS5 over the CPU and another thin layer over the H70 waterblock. Reseated ( no lie the H50/H70 is one of the worst cooler to mount due to the poor design of the screw mounts because the bolt where the screw threads into always comes out of the groove in the back plate and just spins. Hopefuly the H90 ;) will fix this poor design flaw ) the cooler. Idle temps are 40c, 39c, 38c, 39c which is about 10c hotter the I7 920 I recently had with the H50. Load temps after about 30 minutes of World Of Warcraft are 54c, 53c, 54c, 51c. thats what I've been able to test this morning due to the fact I've been fixing PC's all weekend long.... I have not had a chance to run linx or Prime95 yet but judging from what I saw this morning there is no difference. I am however using an Asus Rampage III Extreme and there is an issue with this board and the temperature read out due to Asus poor design of the bios and its a well known issue. I dunno, the H70 really seems like a step down compared to the H50 I was using, louder, cools worse. I dunno maybe its something I am doing but I doubt it. After numerous reseats, etc etc the performance of the cool just seems subpar. Link to comment Share on other sites More sharing options...
CristiM74 Posted December 1, 2010 Share Posted December 1, 2010 I have a similar issue. I'm running an i7 930 @ 4GHz (21x191) @ 1.25V on an Asus Rampage III Extreme with H70 + 2 x Noctua fans. After 10-15 mins. of prime95 on small FFTs I get 80'C. Is this normal? I had higher expectations from this cooler. Link to comment Share on other sites More sharing options...
moskwiz Posted December 14, 2010 Share Posted December 14, 2010 Hi guys.. I can relate to this thread. I just finished installing my new rig - RIIIE, i7 950, H70 ... Tried installing with the stock thermal paste - temps were 45-50 idle - I mean intel stock cooler has the 950 running at the same temps or lower!! On load @ prime95 I got 80c+ in 10 seconds! In Stock?!? Then went on to Arctic Silver 5, remounted the pump unit, tried different positions for the radiator (same slot but tried tubes below and tubes above) - whatever I do though the idle stock temps will not go below 40.. I let the pc prime all night and now it doesn't get above 75c anymore.. what deoes that mean? Thermal paste issue? Pump issue? I'm using a Chieftec Aegis miditower case, and the H70 is installed to the system fan position as intake push/pull, with the above mounted PSU's 14cm fan and the secondary 12cm opt.fan on top doing exhaust. One more thing that's odd - The radiator fans' duty cycle does not affect the cpu temps any whatsoever at all - I even switched them off and looked at idle temps for 10 minutes.. at best the temp rose 1c.. My rooms ambient temp might be around 23-25c, since the H70 is doing intake - that should be good right? Is there any chance my H70 is flawed?

Synthohol Posted December 19, 2010 Share Posted December 19, 2010 http://www.arcticsilver.com/pdf/appmeth/int/vl/intel_app_method_vertical_line_v1.1.pdf never spread the compound on an i7/5/3 read the proper instructions linked above and allow 200 hours before expecting AS5 to do its proper job. there are 168 hours in a week so report back in 10 days when the AS5 has been applied properly and allowed to cure.
